An immobilized cationic rhodium(I) catalyst bearing the diphosphine 1,1'-bis(diisopropylphosphino)ferrocene (DiPFc, 1) allows efficient and chemoselective hydrogenation of a range of functionalized aldehydes, as well as alkenes and alkynes, under mild conditions. This heterogenized catalyst system is convenient to prepare, is stable to air and moisture over extended periods, and is readily recycled.
An Immobilized Homogeneous Catalyst for Efficient and Selective Hydrogenation of Functionalized Aldehydes, Alkenes, and Alkynes. -The new catalyst shown in the scheme allows mild, efficient, and chemoselective hydrogenation of a range of functionalized aldehydes, alkenes, and alkynes [some yields not given.] -(BURK, MARK J.; GERLACH, ARNE; SEMMERIL, DAVID; J.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
