Abstract

L'invention concerne un procédé de préparation de dérivés de l'acide thiophosphorique répondant à la formule I dans laquelle R1 représente un groupe alkyle, X signifie un atome d'hydrogène, de chlore ou de brome, Y1 représente un atome de chlore ou de brome ou un groupe alcoxy et Y2 signifie un atome de chlore ou de brome. Selon le procédé de l'invention on fait réagir, dans un milieu aqueux/organique à 2 phases et en présence d'un alcali et d'un catalyseur de transfert de phase, des composés de formule Il avec des composés de formule III dans laquelle Y3 signifie un atome de chlore ou de brome. Les composés obtenus selon ce procédé sont des produits intermédiaires pour la préparation d'insecticides :The invention relates to a process for the preparation of thiophosphoric acid derivatives corresponding to the formula I in which R1 represents an alkyl group, X means a hydrogen, chlorine or bromine atom, Y1 represents a chlorine or chlorine atom. bromine or an alkoxy group and Y2 means a chlorine or bromine atom. According to the process of the invention, compounds of formula II are reacted in an aqueous / organic medium in 2 phases and in the presence of an alkali and of a phase transfer catalyst with compounds of formula III in which Y3 signifies a chlorine or bromine atom. The compounds obtained according to this process are intermediate products for the preparation of insecticides:
