Fluorodiphenylphosphine

Abstract

Diphenylphosphinous and phenylphosphonous amides both react with benzoyl fluoride to give the corresponding carboxy amide and the mono- or di-fluorophosphine. The difluorophosphine is stable, whereas the monofluorocompound, which can also be prepared by the action of sodium fluoride on chlorodiphenylphosphine in acetonitrile, disproportionates to give the trifluorophosphorane and tetraphenyldiphosphine. The title compound also reacts with benzoyl fluoride to give benzoyldifluorodiphenylphosphorane.
