studies have revealed that anodicoxidation of H-phosphorus compounds occurs first to generate the key P-centered radical directly and cathodic reduction leads to the concurrent release of molecular hydrogen or methane. This protocol features simple operation, broad substrate scope, clean and mild conditions, and atom and step economy to form heterocycle-containing organophosphorus scaffolds.
公开了一种电触发级联环化策略,同时伴随次膦酰化和N-杂环构建。它提供了一种新颖且环保的方法来获得氧膦基取代的N -杂环,无需外部金属催化剂、氧化剂或加热。机理研究表明,H-磷化合物的阳极氧化首先发生,直接产生关键的以 P 为中心的自由基,阴极还原导致分子氢或甲烷的同时释放。该协议具有操作简单、底物范围广、条件清洁温和、原子和步骤经济等特点,可形成含杂环的有机磷支架。
