Rhodium-catalyzed asymmetric phenylation of N-phosphinoylarylimines with triphenylborane

Triphenylborane asymmetrically transfers its phenyl group to N-diphenylphosphinoylarylimines to give diarylmethylamines with high ee in high yield without imine hydrolysis under the catalysis of a chiral amidomonophosphane–rhodium(I) complex.
