Acting together: Low catalytic amounts of CuI and topaquinone‐like catalyst 1ox (see scheme) are sufficient to activate the α‐CH bond of primary amines, which are converted into alkylated imines under ambient conditions. This atom‐economical process tolerates the presence of various reactive functional groups and allows selective cross‐coupling of two amines.
共同作用:低催化量的Cu I和类似topaquinone的催化剂1 ox(请参阅方案)足以激活伯胺的α- CH键,该伯胺在环境条件下会转化为烷基化的亚胺。这种原子经济的方法可以容忍各种反应性官能团的存在,并允许两种胺的选择性交叉偶联。
