intermolecular C-N coupling is reported. The method employs a small-ring organophosphorus-based catalyst (1,2,2,3,4,4-hexamethylphosphetane) and a terminal hydrosilane reductant (phenylsilane) to drive reductive intermolecular coupling of nitro(hetero)arenes with boronic acids. Applications to the construction of both Csp2-N (from arylboronic acids) and Csp3-N bonds (from alkylboronic acids) are demonstrated;
报道了一种通过分子间 CN 偶联合成芳基和杂芳基胺的主要基团催化方法。该方法采用基于小环有机磷的催化剂(1,2,2,3,4,4-六甲基膦烷)和末端氢硅烷还原剂(苯基硅烷)来驱动硝基(杂)芳烃与硼酸的还原性分子间偶联。展示了在构建 Csp2-N(来自芳基硼酸)和 Csp3-N 键(来自烷基硼酸)中的应用;该反应在 Csp3-N 键形成方面是立体有择的。该方法构成了一条从现成的构件到有价值的含氮产品的新途径,与现有催化 CN 偶联方法在范围和化学选择性方面具有互补性。
