We present an efficient silver-catalyzed one-pot controllable molecular editing protocol for the transformation of 2-amino-N-substituted benzamides into 6-selenylated N-substituted 1,2,3-benzotriazine-4(3H)-ones under mild reaction conditions. This three-component strategy is achieved by building N-N/N═N/C-Se bonds, which provides a practical pathway preparation selenylated with broad substrate scope and good functional group tolerance, as well high site-selectivity. Mechanistic experiments suggest that this proceeds via intermolecular site-selective C-H selenylation readily available diselenides, followed annulation using AgNO3 nitrogen synthon.
