Asymmetric hydrogenation catalysed by rhodium complexes of (2R,4R)-bis(diphenylphosphinomethyl)dioxolan. A stable rhodium dihydride derived from a chelating diphosphine complex
Abstract
The mechanism of hydrogenation by rhodium complexes of the diphosphine, (2R,4R)-bis(diphenylphosphinomethyl)dioxolan, is deduced from phosphorus-31 n.m.r. studies.
