摘要：

The asymmetric reduction of benzil to bensoin by cobalt dimethylglyoxime complexes has been studied. The influence of the following parameters: Co:base, Co:chiral base and Co:dmgH2, on the reaction rate, and the value of the enantiomeric excess was evaluated. A mechanism of hydrogenation involving lability of an in-plane dimethylglyoxime ligand is proposed and comparison is made with other possible mechanisms. © 1979.
