Xenondifluoride, XeF2, effectively fluorinates various phosphorous acid derivatives as well as hydrophosphoryl compounds. Arbuzov rearrangement is followed by i-Bu → t-Bu isomerization in the case of i-Bu OPF2.

Abstract The methyl ester of 3-azidotetrafluoropropionic acid, N3-CF2CF2COOMe oxidatively fluorinates P(III), Sb(III) and Te(II) compounds to form the corresponding difluorides in good yield.

Perfluoropropylene (I) efficiently fluorinates esters and ester anhydrides of P(III) and P(V) 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).

alpha,alpha-Difluoroazides react with triphenylantimony and various compounds of trivalent phosphorus according to the oxidative fluorination scheme. In the case of trivalent phosphorus compound the primary products are phosphazenes, phosphazides or difluorophosphoranes that may undergo further transformations to the corresponding fluorine derivatives of pentavalent phosphorus.
