  CuSO₄-Catalyzed Tandem C(sp³)–H Insertion Cyclization of Toluenes with Isonitriles to Form Indoles

  摘要：

  A CuSO4-catalyzed tandem benzylic C-H insertion cyclization of toluene derivatives and isonitriles is described. The naturally abundant salt CuSO4 serves as a low-cost ligand-free redox catalyst. This reaction provides a practical modular synthesis of N-aryl indoles from isonitriles.
