Phosphorus–fluorine chemistry. Part XXI. Pentafluorophenylfluorophosphines and pentafluorophenylfluorophosphoranes

Abstract

The preparation of the fluorophosphines, (C6F5)nPF3–n, and of the fluorophosphoranes, (C6F5)nPF5–n, as well as of the related oxygen species, (C6F5)nP(:O)F3–n(n= 1, 2) is described. 19F and 31P N.m.r. data for the new compounds are reported and discussed.
