Abstract

The synthesis of new epimeric compounds [PdCl(C−N){(±)-PHPhR}] (C−N = (R)-C10H6CHMeNH2 and (R)-C6H4CHMeNH2, R = Me and PhCH2) containing chiral secondary phosphanes is reported. Some of these diastereomers can be separated by column chromatography; subsequent reaction of these complexes with 1,2-bis(diphenylphosphanyl)ethane (dppe) affords the free phosphanes PHBzPh and PHMePh. The configurational stability of the secondary phosphanes resolved has also been studied.
