Article abstract of DOI:10.1016/S0022-1139(00)82059-X

Trialkyldifluorophosphoranes R3PF2 (R = iPr, nBu) were found to react with chlorides or organoelement chlorides, ECl_m or ER_m-zCl_z (E^IV, m = 4, z = 1,2; E^V, m = 3, z = 1,2) of elements belonging to main groups IV and V with chlorine/fluorine exchange to form the halophosphonium salts ⁺Cl^- (X = F, Cl) and the fluoro derivatives, EFm or ERm-zFz.With AlCl3 ionic products of composition are obtained.The transition metal chlorides, NiCl2, PdCl2 NiCl2(PMe3)2, and CoCl2 were found to be less reactive.Chlorine/fluorine exchange has been observed only the case of CoCl2.
