rated carbonyl compounds proved to be a convenient, sim-
ple, and novel method for obtaining excellent chemoselec-
tivity. The unsaturated alcohol was formed with selectivities
up to 99% during cinnamaldehyde hydrogenation under
moderate experimental conditions (25ꢁC, 4 bar). The ben-
eficial role of a significant support effect was interpreted by
