Abstract
Direct cleavage of the N![[double bond, length as m-dash]](https://www.rsc.org/images/entities/char_e001.gif)
N bond of azo compounds by methyltriflate (MeOTf) leading to benzimidazoles has been described. In this reaction, the MeOTf serves as one carbon unit and inserts into the NN bond to form benzimidazole via cleavage of the NN bond and three C–H bonds and meanwhile formation of three C–N bonds.
