(BICYCLO[2.2.1]HEPTA-2,5-DIENE)[(2S,3S)-BIS(DIPHENYLPHOSPHINO)-BUTANE] RHODIUM(I) PERCHLORATE

Uses

(BICYCLO[2.2.1]HEPTA-2,5-DIENE)[(2S,3S)-BIS(DIPHENYLPHOSPHINO)-BUTANE] RHODIUM(I) PERCHLORATE is a catalyst precursor used in the asymmetric hydrogenation of amino acid precursors, as well as in transfer hydrogenation and hydrosilation reactions

Synthesis

Cationic rhodium-chiraphos complexes are usually prepared in situ or from the procedure given below. In reactions employing the various rhodium-chiraphos complexes, the diene ligand is frequently hydrogenated prior to catalysis to afford the active solvated catalyst precursors [RhS2(chiraphos)]+.
