molecules. Although C–H bond acylation has been well-studied via different mechanisms, transition-metal-catalyzed redox-neutral C(sp3)–H acylation under mild conditions is unprecedented. In this work, ketene is designed as a acylating reagent for both C(sp3)–H and C(sp2)–H bonds under Rh(III) catalysis, affording a diverse array of carbonyl compounds in high yields and high atom economy under mild conditions
羰基在功能分子中无处不在。尽管通过不同的机理已经很好地研究了C–H键的酰化作用,但在温和条件下过渡
金属催化的氧化还原中性C(sp 3)–H酰化作用却是空前的。在这项工作中,
乙烯酮被设计为在Rh(III)催化下用于C(sp 3)–H和C(sp 2)–H键的酰化试剂,从而以高收率和高原子经济性提供了各种各样的羰基化合物在温和的条件下。
