A highly efficient, metal-free, chemical oxidation of hydrazines has been implemented using environmentally friendly TCCA as oxidant. This benign protocol provides straightforward access to a wide range of azo compounds in THF in excellent yield. Altogether, 35 azo compounds were obtained in this way and scale-up preparations were performed. Additionally, a plausible mechanism was also proposed. Step-economical
使用环保的TCCA作为氧化剂,已实现了肼的高效,无金属化学氧化。该良性方案可直接获得THF中各种偶氮化合物,且产率极高。以此方式总共获得了35种偶氮化合物,并进行了放大制备。另外,还提出了一种合理的机制。分步经济的过程,温和的反应条件,操作简便,高反应效率和易于放大的规模凸显了该方法的实用性。
