ATTEMPTED PREPARATIONS OF PHOSPHORANES CONTAINING PERFLUOROPHENYL GROUPS

Denney, Donald B.,Denney, Dorothy Z.,Liu, Lun-Tsu

, p. 1 - 8 (2007/10/02)

The reaction of perfluorophenol with phosphorus pentachloride in the presence of triethylamine or χ-collidine yielded perfluoropentaphenoxyphosphorane, 5, along with perfluorotriphenylphosphate, 6, and perfluorodiphenyl ether, 7.Attempts to prepare penta(perfluorobenzyloxy)phosphorane, 12, by a number of methods failed.Similarly attempts to prepare perfluorothiophenylphosphorane, 19, always resulted in perfluorothiophenyl phosphite, 20, and perfluorodiphenyl disulfide, 21.
