was first prepared as an efficient catalyst in Candida Antarctica lipase B (CALB) mediated dynamic kineticresolution (DKR) of secondaryalcohols. With the aid of this ruthenium complex 3, (S)-1-phenylethanol was completely racemized within 25 min, and in combination with CALB, series of secondaryalcohols bearing various functional groups were resolved in an efficient DKR manner.
