Iodine-Catalyzed Oxidative Cross-Coupling of Indoles and Azoles: Regioselective Synthesis of <i>N</i>‑Linked 2‑(Azol-1-yl)indole Derivatives

A highly efficient iodine-catalyzed regioselective oxidative cross-coupling of an indole C–H bond and azole N–H bond is described. This metal-free reaction can be easily carried out at room temperature under mild and environmentally friendly conditions and provides a series of <i>N</i>-linked 2-(azol-1-yl)­indole derivatives in moderate to excellence yields
