Abstract

original image

A tolerant coupling: The title reaction has been developed to deliver arylamines (see scheme; Bz=benzoyl, dppbz=1,2-bis(diphenylphosphino)benzene). The catalysis is based on electrophilic, umpolung amination and enables the use of secondary acyclic amines. Various functional groups are tolerated, thus opening up a new substrate class for the Chan–Lam-type coupling.
