A simple and clean synthesis of polysubstituted 2,6-dicyanoanilines has been developed via the reaction of arylidenemalonodinitriles with 1-arylethylidenemalonodinitriles in ethanol catalyzed by KF/alumina. Use of non-hazardous solid base as a catalyst, operational simplicity and improved product yields are the key advantages of the present protocol.
一种简单清洁的多取代
2,6-二氰基苯胺的合成方法已经开发,该方法通过在KF/铝土矿催化下,在
乙醇中将芳基亚烯稀酸和1-芳基乙基亚烯稀酸反应而成。使用无害的固体碱作为催化剂、操作简便以及提高产率是该方法的主要优势。
