conditions, which is superior to the reported powerful molybdenum system. The reactivity for dehydrogenative coupling reactions of this novel active anode increases when the electrolyte is not stirred during electrolysis. Besides the aryl–aryl coupling, a dehydrogenative arylation reaction of benzylic nitriles was found while stirring the mixture providing quick access to synthetically useful building
在高度稳定的质子介质(如 1,1,1,3,3,3-六氟异丙醇)中运行的活性阳极很少见。在这种独特的溶剂中,镍在恒定电流条件下形成非牺牲活性阳极,优于报道的强大钼系统。当电解期间不搅拌电解质时,这种新型活性阳极的脱氢偶联反应的反应性会增加。除了芳基-芳基偶联之外,在搅拌混合物的同时发现了苄基腈的脱氢芳基化反应,从而可以快速获得合成有用的结构单元。
