摘要:
The present invention provides a process for the preparation of a wide range of primary arylamines. The arylamines are prepared in two efficient, straightforward transformations: 1) an activated aryl group and an imine group are combined, in the presence of a transition metal catalyst, under conditions wherein the transition metal catalyst catalyzes the formation of a carbon-nitrogen bond between the activated carbon of the arene and the imine nitrogen; and 2) the resulting N-aryl imine is transformed, via any of a number of standard protocols, to the primary arylamine. The process of the invention may also be exploited in the preparation of vinylamines.
