, p. 47 - 50 (1995)
Bromophosphonium bromides, R3PBr(+)Br(-) (R = nBu, NMe2, NEt2) are easily fluorinated using zinc difluoride in pyridine or tetramethylammonium fluoride in methylene chloride to give the corresponding difluorophosphoranes R3PF2 in high yield.A simple procedure for preparing pure tetramethylammonium fluoride is described. - Keywords: Preparation; Difluorophosphoranes; Anhydrous zinc; Tetramethylammonium fluorides; NMR spectroscopy
FLUORINATION OF DERIVATIVES OF TRI- AND PENTAVALENT PHOSPHORUS ACIDS BY PERFLUOROPROPYLENE OXIDE
Lermontov, S. A.,Rakov, I. M.,Martynov, I. V.

Perfluoropropylene (I) efficiently fluorinates esters and ester anhydrides of PIII and PV acids to give acid fluoride derivatives of pentavalent phosphorus acids.Phosphites are initially oxidized to the corresponding phosphoryl compounds with subsequent substitution of the oxygen by two fluorine atoms by means of excess oxide (I).
