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.
Addition of CFCl3 to Aromatic Aldehydes via in Situ Grignard Reaction
cost-effective and an environmentally benign strategy for the safe consumption/destruction of the ozone depleting potential of the reagent. In this report, we present a novel method for in situ Grignardreaction using magnesium powder and CFCl3 for synthesis of dichlorofluoromethyl aromatic alcohols.
