| 英文摘要 | Silica-supported methylcellulose-L-alanine-palladium complex (SiO2-MC-LA-Pd) has been prepared and found to be a high optically active catalyst for asymmetric hydrogenation of o-cresol and in-cresol to give (S)-2-methylcyclohexanone and (R)-3-methylcyclohexanone, respectively, at 25degreesC and under an atmospheric hydrogen pressure. The optical yields of (S)-2-methylcyclohexanone and (R)-3-methylcyclohexanone amounted to 91.5 and 68.5%, respectively, when optimum I'd content in SiO2-MC-LA-Pd complex, reaction temperature and solvent were selected. SiO2-MC-LA-Pd catalyst also has shown high stability. The optical yields for (S)-2-methylcyclohexanone and (R)-3-methylcyclohexanone were kept over 90 and 60%, respectively, when the catalyst was reused several times. Moreover, SiO2-MC-LA-Pd complex is an economical catalyst. The methylcellulose is an abundant natural biopolymer and the procedure for preparation of the complex is very simple.
