Synthesis of 2‑Aryl‑2<i>H</i>‑benzotrizoles from Azobenzenes and <i>N</i>‑Sulfonyl Azides through Sequential Rhodium-Catalyzed Amidation and Oxidation in One Pot

Abstract

An efficient synthetic method of 2-aryl-2<i>H</i>-benzotriazoles from nonprefunctionalized azobenzenes and <i>N</i>-sulfonyl azides via sequential Rh-catalyzed amidation (C–N bond formation) and oxidation (N–N bond formation) with PhI­(OAc)₂ in one pot is reported
