Abstract

1346953 1-monosubstituted-carbamoyl-2-benzimidazolyl carbamates CHINOIN GYOGYSZER ES VEGYESZETI TERMEKEK GYARA RT 25 Jan 1972 [25 Jan 1971] 3477/72 Heading C2C A process for preparing a 1-monosubstitutedcarbamoyl-2-benzmiidazolly carbamate of the formula wherein R1 is a (C 1 -C 4 ) alkyl group and R2 is an alkyl, cycloalkyl or aralkyl group, comprises reacting a compound of the formula with an ester of the formula wherein A is a phenyl group substituted by two or more electron-withdrawing groups, in the presence of a base. Suitable examples of A are pentachlorophenyl, 2,4,5-trichlorophenyl and 2- chloro-6-carbamoylphenyl. Suitable bases include inorganic bases such as alkali metal and alkaline earth metal hydroxides, carbonates, bicarbonates as well as tertiary amines such as triethylamine and pyridine. The reaction is preferably carried out in the presence of a solvent. The compounds possess fungicidal and ovicidal activity.
