Mj. Burk et al., An immobilized homogeneous catalyst for efficient and selective hydrogenation of functionalized aldehydes, alkenes, and alkynes, J ORG CHEM, 65(26), 2000, pp. 8933-8939
An immobilized cationic rhodium(I) catalyst bearing the diphosphine 1,1'-bi
s(diisopropylphosphino)ferrocene (DiPFc; 1) allows efficient and chemoselec
tive hydrogenation of a range of functionalized aldehydes as well as alkene
s 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.
