Description

Pentarylene and Hexarylentetracarbonsäurediimide and their preparation

description

The present invention relates Pentarylen- and Hexarylentetracarbonsäurediimide and their preparation and use.

Rylenetetracarboxylic diimides are known to be of particular application interest due to their strong absorption in the near-infrared (NIR) region of the electromagnetic spectrum.

Thus, for example, WO-A 02/77081 describes the use of quaterrylenetetracarboxylic diimides as infrared absorbers for thermal protection in glass laminates.

Pentarylene and hexarylene derivatives, which are unsubstituted or have a low degree of substitution, are described by N.G. Pschirer et al., Angew. Chem. Int. Ed. 45 (2006), 1401-1404.

Similar pentarylene and hexarylene derivatives are also described in DE-A 10 2005 018241.

Despite the already described pentarylene and hexarylene derivatives and their use in connection with their absorption capacity in the NIR, there is a need for further, in particular highly substituted, derivatives and to processes for their preparation.

It is therefore an object of the present invention to provide such derivatives and processes for their preparation which are of particular interest, in particular because of their absorption capacity, and which, owing to the simplest possible production processes, should be easy to prepare despite their comparatively high degree of substitution.

The pentarylene compounds according to the invention have a high degree of substitution, in which the radicals R and R ^A together are present at least five times. However, the sum of the substituents R and R ^A is not more than 8.

The hexarylene compounds according to the invention have a high degree of substitution, in which the radicals R and R ^A together are present at least five times. However, the sum of the substituents R and R ^A is at most 12.

The starting compounds according to the formulas (II), (III), (IIIa) are known from the prior art or can be prepared by means of syntheses of analogous compounds known from the literature. In particular, terrylene and Quaterrylenderivate that can serve as starting materials for the process of the invention for the preparation of pentarylene and Hexarylentetracarbonsäurediimiden are described in the German patent application with the application number 10 2005 021362. In addition, the preparation of hexarylene and Pentarylentetracarbonsäurediimiden in DE-A 10 2005 018241 is described. A preparation of the imide compounds according to the invention can be carried out analogously.

The process according to the invention for the preparation of pentarylene- and hexarylene-tetracarboxylic diimides comprises, as a first step (a), the coupling of at least one rylen- or quaterrylene compound of the formula (II) with at least one compound of the formula (III) or (IIIa), where the linking of the two building blocks takes place in each case with the aid of the groups Y and Y ¹ .

In this case, Y and Y ^{1 may be} halides, by means of which the desired binding of the two aromatic building blocks is made possible with the aid of a catalytic coupling. It is also possible that one of the radicals Y, Y ^{1 may be} a halide and the other a boronic acid or a similar compound of the formula B (OFT) ₂ . A coupling then takes place via the so-called Suzuki reaction. Preferably, in both cases, the halides are bromide or chloride.

The preparation of the diimides according to the invention by means of the process according to the invention is preferably carried out in the presence of an organic solvent, if desired in admixture with water, and a transition metal catalyst and a base, wherein as stated above, one of the two building blocks, a Boronäurede- derivative and the other may represent a halide. Such a boronic acid derivative is obtainable, for example, by reacting the corresponding halogenated aromatic with the aid of diboranes of the general formula (IV) (RO) ₂ BB (OR ^" ) ₂ in the presence of an aprotic organic solvent, a transition metal catalyst and a base.

Aromatic or saturated, and also bicyclic, rings having 5 to 7 C atoms can be fused to the five- or six-membered rings formed as ring members. All rings or ring systems may be substituted by up to 4 C 1 -C ₃₀ -alkyl, C ₅ -C ₈ -cycloalkyl, aryl and / or hetaryl radicals, preferably they are substituted by up to 4 C _r C ₄ -alkyl radicals , Examples of these preferred diboranes are the above-mentioned bis (1, 2 and 1, 3-diolato) -diborane, with bis (pinacolato) diborane being particularly preferred.

The reaction temperature is usually from 20 to 180 ⁰ C, especially at 60 to 120 ⁰ C.

The reaction time is usually 0.5 to 30 hours, in particular 1 to 20 hours.

From a technical point of view, the preparation of the boronic acid derivatives is expediently carried out as follows:

The halogenated aromatic and solvent are added, the diborane of the general formula (IV), the transition metal catalyst and the base are added in succession and the mixture is heated for 0.5 to 30 h under protective gas to the desired reaction temperature. After cooling to room temperature, the solid components are filtered from the reaction mixture and the solvent is distilled off under reduced pressure.

The Suzuki reaction of the boronic acid derivative thus prepared with the corresponding halogenated aromatic can in principle be used under analogous conditions to produce the product in step (a) of the process according to the invention, wherein instead of the diborane the corresponding boronic acid derivative is reacted with the corresponding halogenated aromatic ,

However, the reaction of the boronic acid derivative with the halogenated aromatic is preferably carried out in the presence of an organic solvent, if desired in admixture with water, and of a transition metal catalyst and a base, the molar ratio of boronic acid derivative to halogenated aromatic being generally 0.8: 1 to 3 : 1, preferably 0.9: 1 to 2: 1.

Suitable solvents are all solvents in which the reactants are completely dissolved at reaction temperature and the catalysts and bases used at least partially, so that substantially homogeneous reaction conditions are present.

For example, octane, isooctane, nonane, isononane, decane, isodecane, undecane, dodecane, hexadecane and octadecane are suitable; Cycloheptane, cyclooctane, methylcyclohexane, dimethylcyclohexane, trimethylcyclohexane, ethylcyclohexane, diethylcyclohexane, propylcyclohexane, isopropylcyclohexane, dipropylcyclohexane, butylcyclohexane, tert-butylcyclohexane, methylcycloheptane and methylcyclooctane; Toluene, o-, m- and p-xylene, 1, 3,5-trimethylbenzene (mesitylene), 1, 2,4- and 1, 2,3-trimethylbenzene, ethylbenzene, propylbenzene, isopropylbenzene, butylbenzene, isobutylbenzene, tert. Butylbenzene and cyclobutene lohexylbenzol; Naphthalene, decahydronaphthalene (decalin), 1- and 2-methylnaphthalene, and 1- and 2-ethylnaphthalene; Combinations of the aforementioned solvents, as they can be obtained from the high-boiling, partially or fully hydrogenated fractions of thermal and catalytic cracking processes in crude oil or naphtha, for example mixtures of Exsol ^® type and alkylbenzene Vesso ^® from sol type.

The amount of solvent is usually from 10 to 1000 ml, preferably from 20 to 100 ml per g of boronic acid derivative.

Preferably, water is used as an additional solvent. In this case, 10 to 1000 ml, in particular 250 to 500 ml, of water per I of organic solvent are generally used.

Palladium complexes are likewise preferably used as transition metal catalysts. The amount of catalyst used is usually 1 to 20 mol%, in particular 1, 5 to 5 mol%, based on the boronic acid derivative.

As the base alkali metal salts of weak acids are preferred, the carbonates, such as sodium carbonate and especially potassium carbonate are particularly preferred. Phosphates, such as sodium or potassium phosphate, are also preferred here. In general, the amount of base is from 0.1 to 10 mol, in particular from 0.2 to 5 mol, per mole of boronic acid derivative.

The reaction temperature is generally from 20 to 180 ⁰ C, preferably 60 to 120 ⁰ C. It is used in step b) water, so it is recommended not to carry out the reaction at temperatures above 100 ° C, since it is otherwise possible to operate under pressure.

The reaction is usually completed in 0.5 to 48 hours, especially in 5 to 20 hours.

In terms of process technology, it is expedient to proceed as follows: The boronic acid derivative and the halogenated aromatic as well as solvent are introduced, transition metal catalyst and the base, preferably dissolved in water or a water / alcohol mixture, are added and the mixture is heated for 0.5 to 48 h under protective gas to the desired reaction temperature. After cooling to room temperature, the organic phase is separated from the reaction mixture and the solvent is distilled off under reduced pressure.

The purity of the product thus produced from step (a) of the process according to the invention for the preparation of the pentarylene- and hexarylenetetracarboximides is generally sufficient for the further reaction in step (b). Optionally, the crude product can be further purified by washing with water and, if desired, a suitable organic solvent, in particular a chlorinated aliphatic or aromatic hydrocarbon, or by column chromatography on silica gel with a mixture of methylene chloride and hexane or pentane or with toluene as eluent.

The yield in step a) of the process according to the invention is usually from 20 to 95%.

In addition to the Suzuki reaction described above, which requires a corresponding boronic acid derivative, a direct coupling, in particular in homo couplings, can also be carried out by halides.

In this case, the reaction of the correspondingly halogenated aromatic compounds of the formula (II) and (III) or (IIIa) can be carried out in the presence of a diborane of the general formula (IV). Finally, a Suzuki reaction also takes place, but the corresponding boronic acid derivative is only generated in situ.

The coupling can be carried out, for example, in the presence of 30 to 70 mol%, based on the halogenated aromatic, of a diborane of the general formula (IV), a transition metal catalyst, a base and an aprotic solvent according to a Suzuki coupling reaction, wherein the in In situ formed Boronsäurederivat not intermediately isolated, but is reacted directly with the remaining halogenated aromatic.

In this process variant, the procedure is analogous to the above, but for example, only 30 to 70 mol% of diborane of the general formula (IV), based on the halogenated aromatic used. As a rule, 1 to 20 mol%, preferably 5 to 10 mol%, of transition metal catalyst and 1 to 5 mol, preferably 2 to 3 mol, of base are used per mole of halogenated aromatic th. The aprotic organic solvent is usually used in amounts of from 10 to 100 ml, in particular from 20 to 50 ml, per g of halogenated aromatic compounds.

The reaction temperature is generally from 20 to 100 ⁰ C, preferably at 60 to 80 ⁰ C, and the reaction time at 12 to 72 h, preferably 24 to 48 h.

After cooling to room temperature, the organic phase is separated from the reaction mixture and the solvent is distilled off under reduced pressure.

Again, the purity of the product obtained is usually sufficient for the subsequent cyclodehydration in step (b) of the process according to the invention. Further purification is possible, for example, by column chromatography.

The yield is usually 80 to 95%.

In addition, it is possible to carry out a direct coupling of the halogenated aromatics (halogen compound) without the use of a diborane.

This coupling can take place, for example, in the presence of an organic transition metal complex as a catalyst, free ligand molecules and an aprotic solvent in the sense of a homo-coupling.

Suitable inert diluents are, for example, aliphatic carboxylic acid amides, such as N, N-dimethylformamide and N, N-dimethylacetamide, aliphatic and cycloaliphatic ethers, such as 1,2-dimethoxyethane, and aromatics, such as benzene, toluene and xylene, wherein N, N-dimethylformamide and N, N-dimethylacetamide are preferred.

The amount of diluent is usually 20 to 100 g, preferably 25 to 45 g per gram of halogen compound.

In the case of the organic transition metal complexes serving as catalyst, in addition to the known palladium complexes, such as tetrakis (triphenylphosphine) palladium (0), in particular nickel complexes are suitable, for example bis (triphenyl-) phosphine) nickel (II) chloride, tetrakis (triphenylphosphine) nickel (0), [1, 2-bis (diphenylphosphino) etane] nickel (II) chloride and preferably bis (1, 5-cyclooctadiene) nickel (0). The catalysts can also be obtained by the addition of transition metal salts or compounds, free ligands such as cyclooctadiene, bipyridyl, triphenylphosphine, trifluorophosphine, -η, δ- and π-bonded olefins, cycloolefins, aromatics and antiaromata, carbonyls, hydrogen and Halogen as well as their mixtures and, if necessary, produce oxidizing and reducing agents.

In general, 40 to 150 mol%, preferably 50 to 100 mol%, of organic transition metal complex based on the halogen compound used.

In general, the simultaneous presence of free ligand molecules, in particular mixtures of cyclooctadiene and bipyridyl in the molar ratio of 1: 1 to 8: 1, is always recommended. In this case, amounts of usually 80 to 900 mol%, preferably 80 to 200 mol%, preferably based on the halogen compound suitable.

The coupling temperature is generally 40 to 80 ^° C., preferably 60 to 70 ^° C.

The reaction time is usually 24 to 48 h, in particular 36 to 48 h.

In terms of process technology, this direct coupling is advantageously carried out by initially introducing the halogen compound, the organometallic catalyst and free ligand molecules in the inert diluent and, if appropriate under a protective gas, heating to the desired reaction temperature for 24 to 48 h. After cooling, the reaction mixture in water, which may optionally contain methanol, is a dilute inorganic acid, eg. As dilute hydrochloric acid, and filtered from the precipitate formed, washed with water and dried in vacuo.

The purity of the product according to the invention thus produced is generally sufficient for the subsequent cyclodehydration in step (b) of the process according to the invention. If appropriate, the product can additionally be further purified by column chromatography on silica gel with a mixture of methylene chloride and hexane or pentane as the eluent.

The yield is generally 70 to 90%.

In step (b) of the process according to the invention, the cyclodehydration of the reaction product obtained in step (a) takes place. The Cyclodehydrierung can in a

Potassium carbonate.

In general, the amount of base is 1 to 10 mol, preferably 2 to 5 mol, per mole of starting compound.

The reaction temperature is generally from 40 to 200 ⁰ C, in particular from 80 to 160 ° C.

The reaction time is usually 0.5 to 64 hours, preferably 1 to 12 hours.

In terms of process technology, it is expedient to proceed by stirring a mixture of starting compound, solvent and base under inert gas at the desired reaction temperature for 0.5 to 24 h and the product of the formula (I) or (Ia) according to the invention, after cooling to room temperature, by addition of a Alcohols, such as ethanol, or precipitated by water from the reaction mixture, filtered off and washed with water.
