AbstractMgO-supported chitosan-Rh complex (MgO-CS-Rh) has been prepared and found to be a highly stereoselective catalyst for the asymmetric hydrogenation of some diketones to corresponding chiral alcohols, such as 2,3-butanedione to (2S,3S)-(+)-2,3-butanediol and 2,4-pentanedione to (2S,4S)-(+)-2,4-pentanediol at room temperature and under 1 atm H-2. The optical yield was greatly affected by the Rh content in the complex, the solvent and the reaction temperature. The optical yields of (2S,3S)-(+)-2,3-butanediol and (3S,4S)-(+)-2,4-pentanediol obtained were 87% and 81.2%, respectively. The chiral chitosan-Rh complex catalyst was very easy to prepare, and could be reused without noticeable change in its optical catalytic activity. Copyright (C) 2003 John Wiley Sons, Ltd.
