【摘要】 <正> Complexes generated in situ from Rh(CO)2 (acac)+diphosphine are found to bevery efficient homogeneous catalysts for the hydrogenation of α,β-unsaturated aldehydes andketones into the corresponding saturated carbonyl compounds.In the presence of the chiraldiphosphine(-)-diop,geranial is hydrogenated into(+)-citronellal with optical yield 62%e.e.and neral into(-)-citronellal with 55% e.e.respectively.
