摘要：

A general approach for the alpha-arylation of heteroarenes with nitroarenes via denitrative coupling is reported for the first time. Various heteroarenes, including derivatives of furan, benzofuran, pyrrole, indole, thiophene, and benzothiophene, can be arylated at the alpha-position in moderate to good yields. Mechanistic studies demonstrate that the reaction proceeds via a CMD pathway, with C-H bond activation as the rate-determining step. Furthermore, the scalability and applicability in the synthesis of a drug molecule exemplify the utility of this protocol.
