partial hydrogenation of aniline or nitroarene derivatives and alkylamines is an ideal method for obtaining N-alkylated cyclohexylamine derivatives; however, no such transformations have hitherto been established. Here, we report a highly selective reductive cross-amination using aniline derivatives and alkylamines catalyzed by heterogeneous Rh/Pt bimetallic nanoparticles under mild conditions. The catalyst
苯胺或硝基芳烃衍生物部分加氢生成的亚胺中间体与烷基胺之间的还原性交叉胺化是获得N-烷基化环己胺衍生物的理想方法;然而,迄今为止还没有建立这样的转变。在这里,我们报告了使用苯胺衍生物和烷基胺在温和条件下由非均相 Rh/Pt 双金属纳米粒子催化的高选择性还原交叉胺化。催化剂被回收并重复使用五次,保持高活性。在该反应中,苯胺衍生物部分加氢过程中产生的亚胺中间体被伯烷基胺与催化剂的强烈相互作用立即捕获,导致高度选择性的转化,得到所需的产物,
