英文摘要 | The enantioselective hydrogenation of methyl pyruvate was studied over finely dispersed polyvinylpyrrolidone-stabilized iridium (PVP-Ir) and the corresponding alumina-supported iridium cluster (Al2O3-Ir) modified with cinchonidine. It was found that the modifier, apart from inducing enantioselectivity, has a considerable rate-promoting effect on this reaction with the average rate increased by a actor of 2-3.5 over both the two kinds of catalysts. Favorable reaction parameters were 283 K, 4.0 MPa and alcohols or acetic acid as solvents. Similar to what had been reported in Pt/cinchona system, the highest value of the enantiomeric excess (34.1%) was obtained in acetic acid, accompanied by a marked enhancement of the reaction rate.
