Abstract

1460057 Preparation of carbamates CHINOIN GYOGYSZER ES VEGYESZETI TERMEKEK GYARA RT 23 April 1974 [24 April 1973] 17748/74 Heading C2C Carbamates of the general formula in which R<SP>1</SP> and R<SP>2</SP> are identical or different and each represents a hydrogen atom or an alkyl group of 1-4 C atoms, R represents a halogen atom, aldehyde group or a grouping of the formula in ortho or meta-relation to the carbamoyloxy group, wherein X<SP>1</SP> and X<SP>2</SP> are identical or different and each represents oxygen or sulphur, and R<SP>3</SP> and R<SP>4</SP> are identical or different and each represents alkyl, alkenyl or alkynyl group or R<SP>3</SP> and R<SP>4</SP> are joined such that the whole residue R forms a 5-membered saturated or unsaturated heterocycle which contains X<SP>1</SP> and X<SP>2</SP> as heteroatoms) which comprises reacting a compound of the general formula in the presence of a base with a compound of the general formula in which A represents a phenyl group substituted with 2 or more electron withdrawing groups preferably a pentachlorophenyl group. Preferably the compound of the general Formula II is 2-(1,3-dioxolan-2-yl) phenol in which R<SP>1</SP> is methyl and R<SP>2</SP> is hydrogen. The compounds have insecticidal and accaricidal properties.
