A process for preparing halogenated compounds of formula RCY(Z)CH2CH(X)C(CH3)CH2COR1 where X, Y and Z are halo, R is alkyl, halo, haloalkyl or aryl, and R1 is hydroxy, halo, alkoxy, alkyl or haloalkyl, or the residue of a pyrethroidal alcohol, in which a compound of formula CH2=CHC(CH3)2COR1 is reacted with a sulphonyl halide of formula RCY(Z)SO2X. The process avoids the use of volatile halocarbons in the production of valuable intermediates for insecticides.
Procédé de préparation de composés halogénés de la formule RCY(Z)CH2CH(X)C(CH3)CH2COR1 où X, Y et Z représentent halo, R représente alkyle, halo, haloalkyle ou aryle, et R1 représente hydroxy, halo, alcoxy, alkyle ou haloalkyle, ou le résidu d'un alcool pyréthroïde, dans lequel on fait réagir un composé de la formule CH2=CHC(CH3)2COR1 avec un halogénure sulfonyle de la formule RCY(Z)SO2X. Le procédé permet d'éviter d'utiliser des halocarbures volatils dans la production d'intermédiaires importants pour des insecticides.
