ABSTRACT:
Disclosed are novel phosphine-phosphoramidite compounds which may be employed in combination with a catalytically-active metal to effect a wide variety of reactions such as asymmetric hydrogenations, asymmetric reductions, asymmetric hydroborations, asymmetric olefin isomerizations, asymmetric hydrosilations, asymmetric allylations, asymmetric conjugate additions, and asymmetric organometallic additions. Also disclosed are a process for the preparation of the phosphine-phosphoramidite compounds, metal complex compounds comprising at least one of the phosphine-phosphoramidite compounds and a catalytically-active metal and hydrogenation processes utilizing the metal complex compounds.
