The electrochemical coupling of polyhalogenated compounds with carbonyl compounds is achieved in two ways. A carbanion RX(n)(-) is generated either by the direct electroreduction of RX(n)Cl or by deprotonation of RX(n)H. In this latter case the base Ph(-) is electrogenerated by reduction of iodobenzene. All electrolysis were carried out in an undivided cell fitted with a cadmium-coated cathode and an aluminium or magnesium sacrificial anode. (C) 1997, Elsevier Science Ltd.
