Nickel-catalyzed amidation of aryl alkynyl acids using tetraalkylthiuram disulfides as the amine source is described, affording a series of aryl alkynyl amides in good to excellent yields under mild conditions. This general methodology provides an alternative pathway for the synthesis of useful aryl alkynyl amides in an operationally simple manner, which shows its practical synthetic value in organic synthesis. The mechanism of this transformation was explored through control experiments and DFT calculations.
本文描述了使用四烷基二硫化秋兰姆作为胺源,通过镍催化芳基炔酸的酰胺化反应,在温和条件下以良好至优异的产率得到一系列芳基炔酰胺。这种通用方法以操作简单的方式为有用的芳基炔酰胺的合成提供了一条替代途径,在有机合成中显示出其实际的合成价值。通过对照实验和密度泛函理论(DFT)计算探索了这种转化的机理。
