Abstract
A complex of a cyclic (alkyl)(amino)carbene (CAAC) ligand with chromium catalyzes a mild, chemoselective, and efficient deoxygenative hydroboration of nitro compounds to provide a broad range of anilines, as well as heteroaryl and aliphatic amine derivatives. The CAAC ligand plays an important role in promoting polarity reversal of hydride of HBpin and serves as an H-shuttle.
