synthetic method has been developed for the facile synthesis of 2-substituted benzimidazoles in organized aqueous media in the presence of a surfactant (viz. DBSA) as catalyst and I2 as co-catalyst. The method described has the advantages of operational simplicity, excellent yields, high chemoselectivity, and clean and green reaction profile.
已经开发出一种有效的合成方法,用于在表面活性剂(即DBSA)作为催化剂和I 2作为助催化剂的存在下,在有组织的水性介质中轻松合成2-取代的苯并咪唑。所描述的方法的优点是操作简单,产率高,化学选择性高,反应曲线干净绿色。
