The hydrogenation of N-unsubstituted cyclic imides to the corresponding cyclic amines has been performed selectively with heterogeneous catalysts obtained from rhodium and molybdenum carbonyl precursors. Various substrates were reduced in good to high yields and selectivities. Platinum-based catalysts also proved to be efficient. Furthermore, gram-scale experiments were performed and the catalysts could be recycled.

(Chemical Equation Presented) One for two: [Ru4H 6(p-cymene)4]Cl2 and [RuCl2(p- cymene)]2, [Ru], are efficient catalyst precursors for the selective transformation of cyclic imides into saturated lactams (see scheme). The catalytic systems operate with the same reagent (H2) to perform two transformations, namely, monoreduction of the carbonyl groups and hydrogenation of C=C bonds, with the release only of water, which is the solvent of the reaction.
