电化学氟化是利用电极反应将氟直接引入有机或无机物的一种重要方法。有机物的电化学氟化方法有两种: 一是Simons于1941年发明的, 用镍作阳极, 在无水氟化氢溶液中, 电解制备全氟化合物的方法。此方法在近年来有不少改进。另一是1970年Rozhkov提出的, 以有机溶剂(如含Et3N.3HF的MeCN)为介质, 在铂阳极上,氧化得到单氟化产物的方法。本文全面地综述了这两种方法, 并着重于最新民发展。

Electrochemical fluorination (ECF) is an important means for the introduction of fluorine atom into orgainc or inorganic substractes by electrolytic reaction. For orgainc compounds, two kinds of ECF methdo have been developed. One involves electrolysis in anhydrous HF on Ni to give perfluorinated materials. This method was invented by simons in 1941 and modified greatly in recent years. Another involves fluorinating at Pt in organic solvent(e.g.MeCN containing Et3N.3HF) and yielding mostly monofluorinated derivatives. Such method was realized by Rozhkov in 1970. Our review deals with information concerning both methdos with special emphasis on the recent developments.
