  Pd-Catalyzed Oxidative CH/CH Direct Coupling of Heterocyclic N-Oxides

  摘要：

  A highly efficient protocol for C-H/C-H cross-coupling has been found to occur between 2-aryl-1,2,3-triazole N-oxides and pyridine N-oxide derivatives. In addition, two homocoupling reactions of 2-substituted 1,2,3-triazole N-oxides and some pyridine N-oxide derivatives were developed. A possible pathway of C-H/C-H direct coupling is discussed.
