Azoxyarenes are among important scaffolds in organic molecules. Direct oxidative coupling of primary anilines provides a concise fashion to construct them. However, whether these scaffolds can be prepared from secondary N-alkylanilines is not well explored. Here, we present a catalytic selective oxidative coupling of secondary N-alkylaniline to afford azoxyarene with tungsten catalyst under mild conditions
叠氮芳烃是有机分子中重要的支架之一。初级
苯胺的直接氧化偶联为构建它们提供了一种简洁的方法。然而,这些支架是否可以由仲N-烷基
苯胺制备尚未得到很好的研究。在这里,我们提出了在温和条件下仲N-烷基
