Fluorophosphoranes containing the perfluoropinacolyl ring system. Part II. Synthesis and nuclear magnetic resonance studies

Abstract

The synthesis of fluorophosphoranes containing the perfluoropinacolyl ring system is reported. The i.r. spectra are reported and mass spectra are discussed. The intramolecular exchange of ligands exhibited by these molecules has been studied. The parent trifluorophosphorane is a strong acceptor and complexes have been synthesised with trimethylphosphine and caesium fluoride.
