A simple, green and efficient method has been developed for the synthesis of 5-substituted 1H-tetrazole derivatives through [2+3] cycloaddition reaction in good to excellent yields between various benzonitriles and sodium azide. For this purpose, 1-disulfo-[2,2-bipyridine]-1,1-diium chloride ([BiPy](HSO3)2Cl2) system as an ionic liquid catalyst have been extended for the construction of these valuable
已经开发了一种简单、绿色和有效的方法,用于通过 [2+3] 环加成反应合成 5-取代的 1 H-四唑衍生物,各种苄腈和叠氮化钠之间的收率良好至极好。为此,1-二磺基-[2,2-联吡啶]-1,1-氯化二鎓([BiPy](HSO 3 ) 2 Cl 2)体系作为离子液体催化剂已被扩展用于构建这些有价值的产品. 该程序具有显着优势,包括使用乙二醇作为绿色溶剂。该方法的其他优点是催化剂价格低廉且易于制备,反应条件温和,反应介质绿色,后处理容易,反应时间短,实验过程简单。
