摘要：

A selective hydrogenation of carbon-carbon double bond of alpha,beta-unsaturated ketones are obtained when a mixture of limonene, alpha,beta-unsaturated ketone and 10% Pd/C is refluxed with vigorous stirring for 15-45 min. The best results are obtained when a molar ratio limonene:alpha,beta-unsaturated ketone of 3:1 and 4 molar % palladium/ketone are used. The stereoselectivity is similar to the results obtained when H-2 and Pd/C have been used in neutral solvent.
