Abstract

Potassium hydrogen difluoride reacts with fluorophosphines RnPF3 –n(R = CF3,n= 0–2), to afford salts containing the octahedral fluorohydridophosphate anions [RnPF5 –nH]–. The pentafluorohydridop hosphate ion, [PF5H]–, has also been obtained from reactions between (a) trifluorophosphine and dimethyla mine and (b)(dimethylamino) difluorophosphine and potassium hydrogen difluoride. Dimethylaminolysis of fluorobistrifluoromethyl)phosphine affords (dimethylamino)bis(trifluoromethyl)phosphine and salts of trifluorohydridobis(trifluoromethylphosphate)[(CF3)2PF3H]–, and tetrafluorobis(trifluoromethyl)phosphate ions [(CF3)2PF4]–. 1H and 19F N.m.r. studies confirm the formulae of these novel anions and provide information about their stereochemistry.
