Zusammenfassung:	L'INVENTION CONCERNE LA PREPARATION DE DERIVES ORGANIQUES TRIFLUORO (OU CHLORODIFLUORO OU DICHLOROFLUORO) METHYLES.LE PROCEDE SELON L'INVENTION CONSISTE A REDUIRE PAR VOIE ELECTROCHIMIQUE UN COMPOSE C1FC-BR (X0,1 OU 2) EN PRESENCE D'UN SUBSTRAT ELECTROPHILE NON ELECTROACTIF ET D'UN ELECTROLYTE SUPPORT DANS UN SOLVANT APROTIQUE. A process for the preparation of an organic trihalomethyl derivative comprising electrolytically reducing a compound of the formula: ClxF3-xC-Br in which x is equal to 0, 1 or 2, in a reaction medium also containing an electrophilic substrate which is void of electrochemical activity at the reduction potential of said compound, and a support electrolyte in an aprotic solvent for a time and at a temperature sufficient to form the desired organic trihalomethyl derivative.
