Transfer hydrogenation of unsaturated nitrogen heterocycles using a rhodiumcatalyst immobilized on bipyridine-periodic mesoporous organosilica (BPy-PMO) is described. The immobilized catalyst was prepared by mixing [Cp*RhCl2]2 (Cp* = η5-C5Me5) with BPy-PMO powder in DMF at 60 °C and characterized by nitrogen adsorption measurements, solid-state NMR spectroscopy, X-ray diffraction, energy-dispersive
catalyze the enantioselectivehydrogenation of diverse seven‐membered C=N‐containing heterocyclic compounds (eleven examples; up to 97 % ee). The P‐OP ligand L3, which incorporates an ortho‐diphenyl substituted octahydrobinol phosphite fragment, provided the highest enantioselectivities in the hydrogenation of most of the heterocyclic compounds studied. The observed stereoselection was rationalized by means
