Complexes of the type of have been prepared by the reaction of bis-(?-allylpalladiumchloride) with phosphorous acid disubstituted ethers; their structure has been studied by IR- and NMR- spectroscopy and X-ray analysis.The complexes have a dimeric centro-symmetric structure which is usual for bivalent palladium compounds with a slightly distorted flat-square coordination of the central atom.These compounds are active catalysts for hydrogenation of unsaturated compounds.Complexes of biphosphites of sugars can impart asymmetry in hydrogenation of prochiral substrates.
