Abstract

Selon un procédé de préparation de cyanures de méthylbenzoyle halogénés répondant à la formule (I): PH-CO-CN, dans laquelle Ph désigne un reste phényle substitué par chlorométhyle ou bromométhyle et susceptible de porter le cas échéant 1 à 4 restes supplémentaires, à partir de chlorure de méthylbenzoyle halogéné répondant à la formule (II): PH-CO-Cl, on fait réagir le composé de la formule (II) avec un composé qui libère du cyanure en présence d'un acide de Lewis, le cas échéant dans un solvant ou diluant organique inerte, puis on isole le produit obtenu par ce procédé. Les cyanures méthylbenzoyle halogénés répondant à la formule (I) constituent des produits intermédiaires importants de la synthèse d'agents phytosanitaires.
