A selective transfer hydrogenation of α,β-unsaturated carbonyl compounds to saturated ones in very good yields was achieved by the use of 2-propanol as a hydrogen donor under the influence of catalytic amounts of [Ir(cod)Cl]2, 1,3-bis(diphenylphosphino)propane (dppp), and Cs2CO3. The reduction of carbonyl compounds to alcohols can also promoted by the same catalytic system.
