Oxidativedesulfurization-fluorination of RCH2C(SMe)3 using n-Bu4NH2F3 and 1,3-dibromo-5,5-dimethylhydantoin gave RCHBrCF2SMe in good yields. The products were converted into difluorobromo olefins. Under similar conditions ArCH2C(SMe)3 afforded ArCBr2CF2SMe. The mechanism of the partial difluorination accompanied by bromination is discussed.
