A series of chiral secondary alcohols were easily prepared by means of asymmetric hydrogenation of prochiral aromatic ketones using a new ((Rax)-BuP)/(R,R)-DPEN-Ru(Ⅱ) complex catalyst system. The hydrogenation of 2-methylacetophenone in n-butanol (t-BuOK/Ru=45.6/1, S/C=500, 20atm. Of H2, 20℃, 48h) afforded (S)-1-(2'-methylphenyl)ethanol in 92% ee and>99% conversion.
