(S,S)-Bis(2-hydroxypropyl)(phenyl)phosphane oxide has been prepared, either by ring-opening of (S)-propylene oxide with dilithio(phenyl)phosphane or by catalytic hydrogenation of bis(2-oxopropyl)(phenyl)phosphane oxide, promoted by ruthenium/MeO-BIPHEP. C

The chiral alcohols, (1S)-2-(diphenylphosphoryl)-1-methylethanol (S-Hdpomeo) and (1R)-2-(diphenylphosphoryl)-1-phenylethanol (R-Hdpopeo), have been synthesised in optically pure form by a simple two-step procedure.They can be readily deprotonated and the monoanions L so formed co-ordinate readily to TiIV or MoVI to give complexes of the type , cis- or cis-.The complex crystallised in the orthorombic space group P212121, with a=11.572(1), b=13.209(1), and c=20.452(1) Angstroem.It is octahedral, with trans chlorides, and cis phosphoryl and alkoxide donors.The six-membered chelate rings adopt asymmetric boat conformations, with equatorially projecting methyl groups.This is the first structurally characterised complex containing a phosphorylalkoxide ligand.The NMR spectroscopic evidence suggests retention of the solid-state structure upon dissolution, and considerable rigidity in the chelate rings.
