Ammonia-Borane-Mediated Reduction of Nitroalkenes

Ammonia borane (AB) has been successfully employed in the reduction of nitroalkenes. A variety of nitrostyrenes and alkyl-substituted­ nitroalkenes were chemoselectively reduced to the corresponding nitroalkanes, in short reaction time, with an atom-economic, simple experimental procedure that also works with α- and β-substituted nitroolefins.
