reactivity of acceptor–acceptor diazo malonate reagents is reported using [Ir(cod)Cl]2 as catalyst. A large range of amines, primary and secondary, aliphatic and aromatic, is possible. Mild temperatures, perfect substrate/reactant stoichiometry, and good functional group compatibility render the process particularly attractive for the (late-stage) functionalization of amines.
使用 [Ir(cod)Cl] 2作为催化剂报道了受体-受体重氮丙二酸酯试剂的一般 N-H 插入反应性。可以使用多种胺,伯胺、仲胺、脂族胺和芳族胺。温和的温度、完美的底物/反应物化学计量以及良好的官能团相容性使得该过程对于胺的(后期)官能化特别有吸引力。
