A SELECTIVE REDUCTION OF α,β-UNSATURATED KETONES

Article abstract of DOI:10.1016/S0040-4020(01)80811-5

A selective hydrogenation of carbon-carbon double bond of α,β-unsaturated ketones are obtained when a mixture of limonene, α,β-unsaturated ketone and 10percent Pd/C is refluxed with vigorous stirring for 15-45 min.The best results are obtained when a molar ratio limonene:α,β-unsaturated ketone of 3:1 and 4 molar percent palladium/ketone are used.The stereoselectivity is similar to the results obtained when H2 and Pd/C have been used in neutral solvent.
