Conditions for the palladium–NHC-catalyzed amination of aryl sulfides with aliphatic as well as aromatic amines were established. The KHMDS-mediated amination of heteroaryl sulfides could proceed without palladium. Based on the distinct difference in reactivity of C–Br and C–S bonds, a sequential amination of bromothioanisole can take place to install two different alkylamino groups onto the aromatic
建立了钯-NHC 催化芳基硫化物与脂肪族和芳香族胺胺化的条件。KHMDS 介导的杂芳基硫化物胺化可以在没有钯的情况下进行。基于 C-Br 和 C-S 键反应性的明显差异,可以发生溴苯甲醚的顺序胺化,将两个不同的烷基氨基安装在一个锅中的芳环上。
