A range of novel C2-symmetric dioxygen and dinitrogen ligands can readily be obtained through the interconversion of the parent 1,3-diphenyl- 1,3-propanediol enantiomers which are, in turn, accessed in good yields via a Sharpless asymmetric epoxidative resolution.

(R)-1,2-Bis(diphenylphosphino)phenylethane has been synthesised in good overall yield from (S)-mandelic acid ; its cationic rhodium(I) solvated complex has been shown to be effective in catalytic asymmetric hydrogenation with optical yields of up to 88percent having been observed.The n.m.r. spectra of complexes of this phosphine are discussed.Racemic (R*,R*)-1,3-bis(diphenylphosphino)-1,3-diphenylpropane and (R*,R*)-1,4-bis(diphenylphosphino)-1,4-diphenylbutane have been prepared.These form a range of rhodium complexes with dehydroamino-acids whose structures may be assigned on the basis of characteristic n.m.r.P-Rh and P-P coupling constants.
