Abstract
NEW MATERIAL:A compound of formula I (R1 is H or 1W7C alkyl; R2 is 2,2- dichlorovinyl, 2,2-difluorovinyl, 2,2-dibromovinyl or 1,2-dibromo-2,2-dichloro- ethyl).
USE: An insecticide having a very rapid action with low toxicity to men and cattle.
PROCESS: An alcohol of formula II is reacted with an acid halide of formula III (Y is Cl or Br), preferably an acid chloride, in an inert solvent, e.g. benzene, in the presence of a deacidifying agent, e.g. pyridine, at -30W100°C to give the carboxylic ester of formula I.
