The catalyst system for tandem hydroformylation/hydrogenation of terminal alkenes to the corresponding homologated normal-alcohol was developed. The reaction mechanism for the Rh/Ru dual catalyst was investigated by real-time IR monitoring experiment and 31P NMR spectroscopy, which proved the mutual orthogonality of Rh catalyzed hydroformylation and Ru catalyzed hydrogenation. Detailed investigation about Ru-catalyzed hydrogenation of undecanal under H2/CO pressure clarified different kinetics from the hydrogenation under H2 and gave a clue to design more active hydrogenation catalyst under H2/CO atmosphere. The solely Ru-catalyzed normal-selective hydroformylation/hydrogenation is also reported.
