“…18 Coordinated P-H can react with an M-Cl bond and form a PPh 2 Cl complex. 19 Such facile substitution reactions observed in the chemistry of PPh 2 X ligands, where X is H or a group more electronegative than C, has deterred studies with PPh 2 X ligands.…”

T h er e a c t i o no f[ R u (η 6-cymene)Cl 2 ] 2 and PPh 2 Cl in the ratio 1:2 gives a stable [Ru(η 6-cymene) Cl 2 (PPh 2 Cl)] complex. Attempts to make the cationic [Ru(η 6-cymene)Cl(PPh 2 Cl) 2 ]Cl with excess PPh 2 Cl and higher temperatures led to adventitious hydrolysis and formation of [Ru(η 6-cymene)Cl 2 (PPh 2 OH)]. Attempts to make a phosphinite complex by reacting [Ru(η 6-cymene)Cl 2 ] 2 with PPh 2 Cl in the presence of an alcohol results in the reduction of PPh 2 Cl to give [Ru(η 6-cymene)Cl 2 (PPh 2 H)] and the expected phosphinite. The yield of the hydride complex is highest when the alcohol is 1-phenyl-ethane-1,2-diol. All three half-sandwich complexes are characterized by X-ray crystallography. Surprisingly, the conversion of chlorodiphenylphosphine to diphenylphosphine is mediated by 1-phenyl-ethane-1,2-diol even in the absence of the ruthenium half-sandwich precursor.

The title compound, [RuCl2(η6-C6H6)(C12H22ClP)]·CHCl3, was prepared by reaction of [RuCl2(η6-C6H6)]2 with chlorodicyclohexylphosphane in CHCl3 at 323 K under argon. The RuII atom is surrounded by one arene ligand, two Cl atoms and a phosphane ligand in a piano-stool geometry. The phosphane ligand is linked by the P atom, with an Ru—P bond length of 2.3247 (4) Å. Both cyclohexyl rings at the P atom adopt a chair conformation. In the crystal, the RuII complex molecule and the chloroform solvent molecule are linked by a bifurcated C—H⋯(Cl,Cl) hydrogen bond. Intramolecular C—H⋯Cl hydrogen bonds are also observed.
