Electroorganic reaction in ionic liquids. Part 1: Electrolytic partial fluorination of organic compounds. Part 58. Electroorganic synthesis under solvent-free conditions. Highly regioselective anodic monofluorination of cyclic ethers, lactones, and a cyclic carbonate

Regioselective anodic fluorination of cyclic ethers, lactones, and a cyclic carbonate in Et4NF.nHF (n = 4, 5) and Et3N.5HF without a solvent was successfully carried out to give the corresponding monofluorinated products in moderate yields. This is the first report of direct electochemical fluorination of cyclic ethers, lactones, and a cyclic carbonate using anodic fluorination. (C) 2002 Elsevier Science Ltd. All rights reserved.
