โฆ Synopsis
Reduction of a-fluorosulfides with sodium in alcohol results in the formation of fluoroalkanes. We recently reported a novel synthesis for a-fluorosulfides from thioacetals and mercuric fluoride in acetonitrile at room temperature.' Purification of the unstable a-fluorosulfides proved impossible, thus they were oxidized to the more stable a-fluorosulfoxides. After

A useful conversion of alcohols to alkyl fluorides via their fluoroformates is introduced. The fluoroformates are obtained in nearly quantitative yield from the alcohols by treatment with COF 2 (generated in situ from bis(trichloromethyl) carbonate) in ether with KF as an added acid scavenger. The n
