are readily prepared from the direct reaction between amides and diaryliodonium salts. As demonstrated for 24 different examples, the reaction is of unusually broad scope with respect to the sterically congested arene and the nitrogen source, occurs without the requirement for any additional promoter, and proceeds through a direct reductive elimination at the iodine(III) center. The efficiency of the
由酰胺和二芳基碘鎓盐之间的直接反应可轻松制备2,6-二取代的苯胺。如针对24个不同实例所证明的,该反应相对于空间拥挤的芳烃和氮源而言具有异常宽泛的范围,不需要任何额外的促进剂即可发生,并且通过在碘(III)中心直接还原消除而进行。在凯莫瑞结合抑制剂的短合成中进一步证明了偶联方法的效率。
