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.

Levulinic acid and related γ-ketoacids react with diethylaminosulfur trifluoride to give γ-fluorobutyrolactones in good yield. The involvement of a bicyclic (3.2.1) mechanism is considered.
