A facile nickel-catalyzed method to achieve the amination of synthetically useful aryl sulfamates and carbamates is reported. Contrary to most Ni-catalyzed amination reactions, this user-friendly approach relies on an air-stable Ni(II) precatalyst, which, when employed with a mild reducing agent, efficiently delivers aminated products in good to excellent yields. The scope of the method is broad with respect to both coupling partners and includes heterocyclic substrates.
报道了一种简便的镍催化方法,可实现合成上有用的芳基磺酰胺和氨基甲酸酯的胺化反应。与大多数 Ni 催化的胺化反应不同,这种用户友好的方法依赖于空气稳定的 Ni(II)前催化剂,当与温和的还原剂一起使用时,可有效地以良好至优异的收率得到胺化产物。该方法在偶联伙伴方面具有广泛的适用性,包括杂环底物。
