发明名称 Process for preparing carboxylic acid halogenides and a reaction agent therefor
摘要 The subject of the present invention is a new catalytic system and a process for the synthesis of acid halides, especially from haloforms. This process for halogenation by means of haloform is defined in that there is used, as catalyst, a metal chloride, advantageously trivalent, whose solubility in the reaction mixture is at least equal to one millimole, preferably 1/100 mole per litre, the said metal chloride being at least half, advantageously two thirds, preferably three quarters, in the dissolved state. Application to organic synthesis.
