proposed to use the quantity ΔJ/JL(ΔJ=Jc–JL; Jc= P–F or P–H coupling constant of the co-ordinated ligand; JL= P–F or P–H coupling constant of the free ligand) as a measure of the π-donor strength of the metal carbonyl fragments, M(CO)x(M = Ni, x= 3; M = Cr, W, x= 5; or M = Mo, x= 3–5).

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.
Fluorination of derivatives of tri- and pentavalent phosphorus acids by perfluoropropylene oxide

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).
