A novel S8-mediated approach to benzothiazoles/benzoselenazoles from bis(2-aminophenyl) disulfides/diselenides and phenylacetylenes or styrenes has been developed. 2-(Arylmethyl)-1,3-benzoselenazoles were comprehensively synthesized for the first time. The reactions proceeded in moderate to excellent yields, and with a gram-scale application.
已经开发了一种从双(2-氨基苯基)二硫化物/二硒化物和苯乙炔或苯乙烯中提取苯并噻唑/苯并硒唑的新型 S8 介导方法。首次综合合成了2-(芳甲基)-1,3-苯并硒唑。反应以中等至极好的产率进行,并具有克级规模的应用。
