A switchable oxidative coupling reaction of isocyanide and peroxide has been disclosed. In the presence of iron catalyst, the coupling reaction affords N‐arylacetamides in good yields. By simply replacing the iron with copper catalyst, another different coupling reaction takes place in which peroxide can serve as alkoxylating source. This protocol represents a new fundamental coupling of two basic
已经公开了异氰酸酯和过氧化物的可切换的氧化偶联反应。在铁催化剂存在下,偶联反应可提供高收率的N-芳基乙酰胺。通过简单地用铜催化剂代替铁,就会发生另一种不同的偶联反应,其中过氧化物可以用作烷氧基化源。该协议代表了涉及C-C和C-O键形成过程的两种基本化学物质的新的基本耦合。自由基反应中异氰基的异常反应也已正式确立,而自由基反应在形式上起酰胺基合成子的作用。实验结果表明,在目前的偶联反应中,芳族异氰酸酯是特别相容的反应伙伴,而当使用脂族异氰酸酯时,没有观察到所需的产物。
