We report herein that suitably supported perfluorosulfonic acids can catalyze the oxidative dimerization of anilines using hydrogen peroxide as a clean oxidant. The reaction does not require the use of organic solvents and affords desired azobenzenes and water as products, minimizing the formation of wastes. The metal-free solid catalyst shows remarkable activity and selectivity for the reaction, which occurs under very mild conditions and with broad functional group tolerance.

均相磺酸催化剂对苯胺的氧化二聚作用

我们在本文中报道，使用过氧化氢作为清洁氧化剂，适当负载的全氟磺酸可以催化苯胺的氧化二聚作用。该反应不需要使用有机溶剂，并提供所需的偶氮苯和水作为产物，使废物的形成最小化。不含金属的固体催化剂对反应显示出显着的活性和选择性，这在非常温和的条件下发生，并且具有宽泛的官能团耐受性。
