By addition of cyanide, a carbonyl compound AD-1 can be transformed into its cyano hydrine (see e.g. Chemistry A Eur. J. (201 1 ), 17(44), 12276-12279; Eur. J. Org. Chem. (2002), (19), 3243-3249; Synlett (2003), (3), 353-356; Chirality (2009), 21 (9), 836-842; or J. Org. Chem. (2008), 73(18), 7373-7375). Reduction of the nitrile group provides compounds AD-3.
Depending on the reaction conditions, the nitrile in AD-3 can be reduced and the hydroxyl group be removed in one step to furnish compounds III, wherein R2, R3 and R4 are hydrogen (see e.g. Justus Liebigs Annalen der Chemie (1949), 564, 49-54, Justus Liebigs Annalen der Chemie (1957), 605, 200-1 1 , J.

(1948), 70, 3738-40, J. Am. Chem. Soc. (1933), 55, 2593-7; Tetrahedron (2001 ), 57(40), 8573-8580, Chem. Pharm. Bull. (2003), 51 (6), 702-709). This hydroxyl group can be
transformed in a further step to provide halogen, cyano (Tetrahedron Lett. (2007), 48(38), 6779- 6784), amino or alkoxy groups by nucleophilic substitution in compounds III, wherein R3 and R4 are hydrogen and R2 is halogen, CN or Ci-C4-alkoxy.

The terminal nitro group can be reduced selectively in the presence of the nitrile to yield compounds III, wherein R2 is Ci-C4-alkoxy or CN, respectively.
It may be advantageous to couple AD-1 with a heterocycle Het-LG prior to the
abovementioned reactions as shown in Scheme 2.

Furthermore, substituted benzyl nitriles AD-9, which are available from benzyl halides AD-8, can be used as intermediates for the preparation of compounds III, wherein R2, R3 and R4 are hydrogen, according to scheme 7 by way of reduction with an appropriate reducing agent (e.g. UAIH4, PhSiHs or H2 and a catalyst) as shown in Scheme 7 (Tetrahedron (201 1 ), 67(42), 8183- 8186; WO 201 1/088181 ; Eur.

Further, compounds AD-9 can be used to obtain compounds III, wherein at least one group R3 or R4 are not hydrogen.

Suitable bactericides are bronopol and isothiazolinone derivatives such as alkyliso- thiazolinones and benzisothiazolinones.
Suitable anti-freezing agents are ethylene glycol, propylene glycol, urea and glycerin.
Suitable anti-foaming agents are silicones, long chain alcohols, and salts of fatty acids.
Suitable colorants (e.g. in red, blue, or green) are pigments of low water solubility and water- soluble dyes. Examples are inorganic colorants (e.g. iron oxide, titan oxide, iron
hexacyanoferrate) and organic colorants (e.g. alizarin-, azo- and phthalocyanine colorants).
Suitable tackifiers or binders are polyvinylpyrrolidons, polyvinylacetates, polyvinyl alcohols, polyacrylates, biological or synthetic waxes, and cellulose ethers. The agrochemical compositions generally comprise between 0.01 and 95%, preferably between 0.1 and 90%, and most preferably between 0.5 and 75%, by weight of active substance. The active substances are employed in a purity of from 90% to 100%, preferably from 95% to 100% (according to NMR spectrum).
Water-soluble concentrates (LS), Suspoemulsions (SE), flowable concentrates (FS), powders for dry treatment (DS), water-dispersible powders for slurry treatment (WS), water- soluble powders (SS), emulsions (ES), emulsifiable concentrates (EC) and gels (GF) are usually employed for the purposes of treatment of plant propagation materials, particularly seeds. The compositions in question give, after two-to-tenfold dilution, active substance concentrations of from 0.01 to 60% by weight, preferably from 0.1 to 40%, in the ready-to-use preparations.
Application can be carried out before or during sowing. Methods for applying or treating compound I and compositions thereof, respectively, on to plant propagation material, especially seeds include dressing, coating, pelleting, dusting, soaking and in-furrow application methods of the propagation material. Preferably, compound I or the compositions thereof, respectively, are applied on to the plant propagation material by a method such that germination is not induced, e. g. by seed dressing, pelleting, coating and dusting.
When employed in plant protection, the amounts of active substances applied are, depending on the kind of effect desired, from 0.001 to 2 kg per ha, preferably from 0.005 to 2 kg per ha, more preferably from 0.05 to 0.9 kg per ha, in particular from 0.1 to 0.75 kg per ha.
In treatment of plant propagation materials such as seeds, e. g. by dusting, coating or drenching seed, amounts of active substance of from 0.1 to 1000 g, preferably from 1 to 1000 g, more preferably from 1 to 100 g and most preferably from 5 to 100 g, per 100 kilogram of plant propagation material (preferably seed) are generally required.
When used in the protection of materials or stored products, the amount of active substance applied depends on the kind of application area and on the desired effect. Amounts customarily applied in the protection of materials are 0.001 g to 2 kg, preferably 0.005 g to 1 kg, of active substance per cubic meter of treated material.
Various types of oils, wetters, adjuvants, fertilizer, or micronutrients, and other pesticides (e.g. herbicides, insecticides, fungicides, growth regulators, safeners) may be added to the active substances or the compositions comprising them as premix or, if appropriate not until immediately prior to use (tank mix). These agents can be admixed with the compositions according to the invention in a weight ratio of 1 :100 to 100:1 , preferably 1 :10 to 10:1.
The user applies the composition according to the invention usually from a predosage device, a knapsack sprayer, a spray tank, a spray plane, or an irrigation system. Usually, the agrochemical composition is made up with water, buffer, and/or further auxiliaries to the desired application concentration and the ready-to-use spray liquor or the agrochemical composition according to the invention is thus obtained. Usually, 20 to 2000 liters, preferably 50 to 400 liters, of the ready-to-use spray liquor are applied per hectare of agricultural useful area.
According to one embodiment, individual components of the composition according to the invention such as parts of a kit or parts of a binary or ternary mixture may be mixed by the user himself in a spray tank and further auxiliaries may be added, if appropriate.
Mixing the compounds I or the compositions comprising them in the use form as fungicides with other fungicides results in many cases in an expansion of the fungicidal spectrum of activity being obtained or in a prevention of fungicide resistance development. Furthermore, in many cases, synergistic effects are obtained.

The present invention furthermore relates to agrochemical compositions comprising a mixture of at least one compound I (component 1 ) and at least one further active substance useful for plant protection, e. g. selected from the groups A) to O) (component 2), in particular one further fungicide, e. g. one or more fungicide from the groups A) to L), as described above, and if desired one suitable solvent or solid carrier. Those mixtures are of particular interest, since many of them at the same application rate show higher efficiencies against harmful fungi. Furthermore, combating harmful fungi with a mixture of compounds I and at least one fungicide from groups A) to L), as described above, is more efficient than combating those fungi with individual compounds I or individual fungicides from groups A) to L). By applying compounds I together with at least one active substance from groups A) to O) a synergistic effect can be obtained, i.e. more then simple addition of the individual effects is obtained (synergistic mixtures).
This can be obtained by applying the compounds I and at least one further active substance simultaneously, either jointly (e. g. as tank-mix) or separately, or in succession, wherein the time interval between the individual applications is selected to ensure that the active substance applied first still occurs at the site of action in a sufficient amount at the time of application of the further active substance(s). The order of application is not essential for working of the present invention.
