Abstract: The asymmetric hydrogenation of benzalacetone catalyzed by RuCl2(TPPTS)2-(S,S)-DPENDS in water medium was investigated. The selectivity of 96.0% for 4-phenyl-3-butene-2-ol and ee value of 71.2% were obtained. The catalyst could be reused five times without evident loss of catalytic activity and enantioselectivity.

Key words: ruthenium monophosphine complex, benzalacetone, water medium, asymmetric hydrogenation, enantioselectivity
