An organocatalytic, highly facile, efficient, and regioselective ortho‐chlorination of anilines is described. A secondary ammonium chloride salt has been employed as the catalyst and the reaction can be conducted at room temperature without protection from air and moisture. In addition, the reaction is readily scalable and the catalyst can be recycled and reused. This catalytic protocol has been applied
描述了苯胺的有机催化,高度简便,有效和区域选择性邻氯化反应。已经使用仲氯化铵盐作为催化剂,并且该反应可以在室温下进行而无需保护空气和湿气。另外,该反应易于扩展,并且催化剂可以再循环和再利用。该催化方案已用于高效合成高效c-Met激酶抑制剂。机理研究表明,仲氯化铵盐的独特结构特征对于亲电子邻氯化反应的催化和区域选择性均很重要。
