Abstract
An easy and generalized route to 2(3H)‐benzimidazolones, 2(3H)‐benzoxazolone and 2(3H)‐benzothiazolone is attempted. A novel one‐pot method for the in situ generation and cyclisation of ortho substituted benzoic acid azides is reported via the application of ammonium azide and Vilsmeier complex.
