We report herein a highly efficient Pd-catalyzed amination by “bulky-yet-flexible” Pd-PEPPSI-IPentAn complexes. The relationship between the N-heterocyclic carbenes (NHCs) structure and catalytic properties was discussed. Sterically hindered (hetero)arylchlorides and a variety of aliphatic and aromatic amines can be applied in this cross-coupling, which smoothly proceeded to provide desired products
我们在此报告了一种由“大体积但还灵活”的Pd-PEPPSI-IPent An复合物进行的高效Pd催化胺化反应。讨论了N-杂环卡宾(NHCs)结构与催化性能之间的关系。可以在该交叉偶联中应用立体受阻的(杂)芳基氯化物以及各种脂肪族和芳香族胺,它们可以顺利进行以提供所需的产物。操作简单的协议强调了在不排除空气和水分的情况下,在温和条件下可快速获得C Ar -N键的形成。
