文摘A series of chiral salen\|Co(Ⅱ) complexes have been synthesized and characterized, and they are for the first time used as the catalyst for asymmetric borohydride reduction of aromatic ketone. Enantiometric exesses up to 28.2% have been achieved at the room temperature. The influence of substituent on enantioselectivity of the reactions was studied.
