A new approach to the synthesis of 2,2-difluoro-1,3-dioxolanes

Abstract A direct and versatile way to prepare halogenated 2,2-difluoro-1,3-dioxolanes through the addition of bis-(fluoroxy)difluoromethane (BDM) to halogenated alkenes (CF2CFCF3, CF2CFOCF2CF3, CF2CHCF3, CF3CFCFCF3, CFClCFCl, CFBrCFBr, CCl2CCl2, CHClCCl2, CHClCHCl, CH2CHCl, CF2CFCl, (CF3)2CFCFCFCF3, CF2CFBr, CF2CF2) has been discovered.
