Abstract
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 halogenating by means of a haloform is characterized by the use of a metal chloride, advantageously trivalent, as a catalyst, the solubility of which in the reaction mixture is at least equal to one millimole, preferably 1/100 mole per liter, and the metal chloride also being at least half, advantageously two-thirds and preferably three-quarters in the dissolved state.
