ELECTROCHEMICAL FLUORINATION

摘要

A process for the production of a compound of the formula: R-On-(R<1>)m-CHF2 wherein R is hydrogen or a fluorine containing C1-4 alkyl group, R1 is an optionally fluorinated methylene group, and m and n are independently 0 or 1 provided that where n = 0, m = 0 and that where n = 1, R is not hydrogen, comprising subjecting a compound of the formula: R-On-(R<1>)m-CH2F wherein R, R<1>, m and n have the definitions above to electrochemical fluorination in liquid hydrogen fluoride electrolyte.
