A catalyst system capable of effecting the cross-coupling of ammonia or primary alkylamines with (hetero)arylsulfamates, carbamates, or pivalates is reported for the first time. The air-stable nickel(II) pre-catalyst C1 tolerates a broad spectrum of heterocyclic functionality within both reaction partners, as well as ether, nitrile, pyrrole, trifluoromethyl, and boronate ester substituents. In the
首次报道了能够实现氨或伯烷基胺与(杂)芳基氨基磺酸酯、氨基甲酸酯或新戊酸酯交叉偶联的催化剂体系。空气稳定的镍 (II) 预催化剂 C1 可耐受两种反应伙伴以及醚、腈、吡咯、三氟甲基和硼酸酯取代基中的广谱杂环官能团。在涉及伯烷基胺和(杂)芳基氨基磺酸酯和氨基甲酸酯的反应的情况下,实现了室温交叉偶联。
