It was found that dibromo-2,2,3,3-tetrafluoropropoxydifluorophosphorane, obtained from 2,2,3,3-tetrafluoropropyl difluorophosphite and bromine, adds two moles of chloral or bromal with the formation of stable 2,2,3,3-tetrafluoropropoxybis(1-bromo-2,2,2-trihaloethoxy)difluorophosphoranes, the structure of which was confirmed by NMR data. © 1991 Plenum Publishing Corporation.
