An improved synthesis of ferrocenyldimethylphosphine, FcPMe2, is limited only by the unreliable literature procedure for preparlng precursor dichloroferrocenylphosphine, FcPCl2. The latter compound yields a crystalline copper(I) iodide complex on reaction with lithium dimethylcuprate. Methanolysis of FcPCl2 yields unstable dimethyl ferrocenylphosphonite, FcP(OMe)2, which is converted to methyl ferrocenylphosphinite, FcPH(O)OMe, on heating or chromatography.

A variety of dihalodiphosphinenickel(II) complexes have been found to be effective catalysts for hydrosilylation of olefins and acetylenes. Reactions with nickel(II) catalysts, at least those containing a bidentate phosphine ligand, scarcely proceed below 90°. At 120° the reaction proceeds smoothly to form, in many cases, an unexpected (“abnormal”) adduct which has arisen from an interchange of hydrogen

[RuCl2(κ-P*-η6-arene)] compounds. Full characterization of all compounds both in solution and in the solid state has been carried out. Crystal structure determinations of four phosphine–borane molecules confirm the S configuration at the phosphorus atom (1a,e,l and 2d). Moreover, the crystal structure of one p-cymene complex (5i) and four tethered complexes reveal the strain of the compounds with two atoms
