  • the chlorination catalyst is used in the process according to the invention in a concentration of 0.1 to 20 mol%, preferably 0.1 to 10 mol%, particularly preferably 0.5 to 5 mol%, based on the lactone (II).
  • the process according to the invention enables chlorocarboxylic acid chlorides to be prepared by reacting the corresponding lactones with a chlorinating agent which makes the chlorocarboxylic acid chlorides accessible in high yield and high purity and no longer has the disadvantages of additionally introducing hydrogen chloride gas.
  • the chlorocarboxylic acid chlorides can be easily separated from the boron compounds added according to the invention during workup.

Abstract

L'invention concerne un procédé de production de chlorures d'acide chlorocarboxylique correspondant à la formule (I), dans laquelle R1 et R2 représentent, indépendamment l'un de l'autre, un atome d'hydrogène, un reste organique contenant du carbone, un halogène, un groupe nitro ou un groupe cyano, et Y représente une chaîne alkylène C¿1?-C10, non substituée ou bien substituée par des restes organiques contenant du carbone, par halogène, ou par des groupes nitro et/ou cyano, cette chaîne alkylène pouvant être interrompue par un groupe éther, thioéther, amino ou céto tertiaire. Les restes organiques contenant du carbone de Y et/ou R?1¿ et/ou R2 peuvent être liés avec formation d'un système non aromatique. Selon ledit procédé, on produit les chlorures d'acide chlorocarboxylique en faisant réagir une lactone correspondant à la formule (II), dans laquelle R1, R2 et Y ont la signification donnée ci-dessus, avec un agent de chloration, en présence d'un catalyseur de chloration, cette réaction étant conduite en présence d'un composé de bore.
