A process for the preparation of cyclopropane carboxylic acid derivatives of the formula STR1 wherein Z is selected from the group consisting of --CN, --COOH and --COOR1, R1 is alkyl of 1 to 6 carbon atoms and R2 and Rsub
Preparation of substituted alpha-halogeno-propionic acids and their derivatives
-
, (2008/06/13)
Substituted α-halogenopropionic acids and their derivatives of the general formula STR1 wherein R1 to R3, Y and X have the meanings given in the description, are prepared by a process which is characterized in that substituted vinylidene chlorides of the general formula STR2 are reacted with chlorine or bromine chloride in the presence of compounds of the formula wherein R5 and R6 have the meaning given in the description, and the products obtained are treated, if appropriate, with water or alcohol. Certain of the substituted α-halogeno-propionic acids and the substituted vinylidene chloride of the formula STR3 are new. The end products are useful as herbicides and intermediates for insecticides.
