On August 6, 2021, Liu, Lu; Li, Lei; Wang, Xin; Sun, Ran; Zhou, Ming-Dong; Wang, He published an article.Reference of 2-(2-Nitro-4-(trifluoromethyl)phenyl)acetonitrile The title of the article was Mn(III)-Mediated Radical Cyclization of o-Alkenyl Aromatic Isocyanides with Boronic Acids: Access to N-Unprotected 2-Aryl-3-cyanoindoles. And the article contained the following:

The synthesis of N-unprotected 2-aryl-3-cyanoindoles was realized via the Mn(III)-mediated radical cascade cyclization of o-alkenyl aromatic isocyanides with boronic acids. A possible mechanism involving a sequential intermol. radical addition, intramol. cyclization, and cleavage of the C-C bond under mild reaction conditions is proposed. Mechanism studies show that H2O or O2 might provide the oxygen source for the elimination of benzaldehyde. The experimental process involved the reaction of 2-(2-Nitro-4-(trifluoromethyl)phenyl)acetonitrile(cas: 13544-06-4).Reference of 2-(2-Nitro-4-(trifluoromethyl)phenyl)acetonitrile
