Abstract

2,2-Dichloro- and 2,2-dibromo-cyclopropane carboxylic acids and substitution products thereof are prepared by the action of an alkali-metal salt of trichloro -or tribromo-acetic acid on an alkyl ester of an unsaturated acid of the formula R(R1)C=C(R11)COOH, in which R, R1 and R11 are hydrogen atoms or alkyl or aryl groups, in any permutation, followed by alkaline or acid hydrolysis of the resulting 2,2-dichloro- or 2,2-dibromo-cyclopropane carboxylic ester to yield the free acid. In the examples, (1) methyl methacrylate and sodium trichloracetate yield methyl 1-methyl-2, 2-dichlorocyclopropane carboxylate, which is hydrolysed with hydrochloric acid to yield the free acid; (2) ethyl cinnamate and sodium trichloracetate yield ethyl trans-2, 2-dichloro -3- phenylcyclopropane carboxylate, which is hydrolysed with hydrochloric acid to yield the free acid; the corresponding 2,2-dibromo compound is obtained if sodium tribromoacetate is used instead of sodium trichloracetate. Specification 978,351 is referred to.
