Jagadeesha, Gullahalli S. published the artcileMicrowave-Assisted, Metal-Free, Chemoselective N -Formylation of Amines using 2-Formyl-3-methyl-1H-imidazol-3-ium Iodide and In Situ Synthesis of Benzimidazole and Isocyanides, SDS of cas: 56-05-3, the publication is SynOpen (2022), 6(2), 132-140, database is CAplus.
An efficient, environmentally benign, chemoselective, microwave-assisted N-formylation protocol of aromatic, aliphatic, alicyclic, benzylic amines, inactivated aromatic amines and sterically demanding heterocyclic amines using 2-formyl-1,3-dimethyl-1H-imidazol-3-ium iodide were developed. This afforded a series of N-substituted formamides RR1NCHO [R = H, Me, Bn, R1 = Me, t-Bu, Bn, etc., RR1 = (CH2)4, (CH2)5; R = H, R1 = Ph, 4-MeC6H4, 4-BrC6H4, etc.] with good to excellent yields (23 examples, 53-96% yield) and was readily scaled. The methodol. were further extended to synthesize benzimidazole and isocyanide derivatives
