Cobalt(II)-Catalyzed C-H Amination of Arenes with Simple Alkylamines.

A new method of cobalt-catalyzed amination of arylamides with simple alkylamines is reported through C(sp2)–H bond functionalization. For the first time, inexpensive cobalt is exploited as the catalyst in the amination of C(sp2)–H bond using simple alkylamines.
