Document Type and Number:
WIPO Patent Application WO2006012046
Kind Code:
A3
Abstract:
Disclosed is a process for the preparation of phosphine-aminophosphines that are useful in the formation of catalysts useful in carrying out 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. The process comprises the steps of (1) contacting a compound of formula (2): R
