The direct dehydrogenation of alkanes is among the most efficient ways to access valuable alkene products. Although several catalysts have been designed to promote this transformation, they have unfortunately found limited applications in fine chemical synthesis. Here, we report a conceptually novel strategy for the catalytic, intermolecular dehydrogenation of alkanes using a ruthenium catalyst. The combination
烷烃直接脱氢是获得有价值的烯烃产品的最有效方法之一。尽管已经设计了几种催化剂来促进这种转变,但不幸的是它们在精细化学合成中的应用有限。在这里,我们报告了一种使用钌催化剂催化烷烃分子间脱氢的概念新颖的策略。氧化还原活性配体和空间位阻芳基自由基中间体的组合释放了这种新策略。重要的是,已经进行了机理研究,为进一步开发这种新型催化脱氢系统提供了概念框架。
