Organic reactions catalyzed by solid superacids. 10. Perfluorinated sulfonic acid resin (Nafion-H) catalyzed ring closure reaction of 2,2'-diaminobiphenyls. A preparative route to carbazoles
We have developed a heterogeneous catalytic oxidative homocoupling reaction of dimethoxyanilides under an oxygen atmosphere. The resulting homo-dimers are useful for the construction of heterocycles, demonstrating the potential of heterogeneous metal catalysts.
