Title (EN) AROMATIC THIOETHER ACYLATION METHOD
(FR) PROCEDE D'ACYLATION D'UN THIOETHER AROMATIQUE
Abstract:
(EN) An aromatic thioether acylation method is disclosed. In a preferred embodiment, the method comprises condensing acetic anhydride or acetyl chloride with thioanisole. According to said aromatic thioether acylation method, said thioether is reacted with an acylating agent selected from the group which consists of carboxylic acid halides and carboxylic acid anhydrides, in the presence of an effective amount of an acid zeolite.
(FR) La présente invention a pour objet un procédé d'acylation d'un thioéther aromatique. Dans sa variante préférée, l'invention réside dans un procédé de condensation de l'anhydride acétique ou du chlorure d'acétyle avec le thioanisole. Le procédé d'acylation d'un thioéther aromatique selon l'invention est caractérisé par le fait qu'il consiste à faire réagir ledit thioéther avec un agent d'acylation choisi dans le groupe formé par les halogénures d'acides carboxyliques et les anhydrides d'acides carboxyliques, en présence d'une quantité efficace d'une zéolithe acide.
