A novel direct transformation of aliphatic terminal alkynes to alkenyl nitriles through the incorporation of a nitrogen atom into the simple hydrocarbons has been reported. The usage of inexpensive copper catalyst, O2 as the sole oxidant, broad substrate scope as well as feasibility for “late-stage modification” make this protocol very promising. Mechanistic studies including DFT calculation demonstrate
已经报道了通过将氮原子结合到简单的烃中,将脂肪族末端炔烃直接转化为烯基腈的新方法。使用廉价的铜催化剂、O 2作为唯一氧化剂、广泛的底物范围以及“后期修改”的可行性使该协议非常有前景。包括 DFT 计算在内的机理研究证明了这种新型氮化反应的新型 1,2-氢化物变换过程。
