Biphasic hydrogenation of olefins, dienes, and α,β-unsaturated carbonyl compounds catalyzed by the dimer of chloro(1,5-hexadiene)rhodium

Abstract
Olefins, dienes, and trienes can be hydrogenated in an aqueous–organic two-phase medium using the dimer of chloro(1,5-hexadiene)rhodium as the catalyst. Selective reduction of the double bond of α,β-unsaturated carbonyls occurs in high yields. These reactions occur at room temperatures and atmospheric pressure, and are simple to work-up.
