PROCESS FOR THE PREPARATION OF ACID CHLORIDE COMPOUNDS.

摘要

The invention refers to an effective and efficient process for the preparation of azinyl acid chloride of formula I, (the Az ring is found defines in the description). In this process, a trichloromethylazine of formula II is treated with an acid which is capable of forming an acid chloride that can be separated by distillation during the course of the reaction under reduced low pressure in the presence of acid catalyst and refers to the use of the compounds of the formula I and obtained in accordance with this process for the preparation of (hetero)aryloxyazinylcarboxamides.
