摘　　要：二芳基碘盐具有毒性低、反应条件温和及选择性高的优点,在有机合成中一直受到关注,已被广泛用作芳基化试剂,可用于芳杂环化合物的交叉偶联反应和芳基化反应等.发展了一种铜催化下苯并噻唑与二芳基碘鎓盐反应合成2-芳基苯并噻唑衍生物的方法.该方法具有底物范围广泛、基团耐受性良好及产率高等优点.Diaryliodonium salts have low toxicity and good stability,and their mediated reactions often have advantages of mild reaction conditions and high selectivity.They have received extensive attention and have been widely used as arylating agents in organic synthesis.A simple and efficient method for the synthesis of 2-arylbenzothiazole derivatives via copper-catalyzed C-H direct arylation of benzothiazoles with diaryliodonium salts as electrophilic arylating reagents was developed.This method shows wide range of substrates,good group tolerance,simple operation and high product yields.
