<b>A green and efficient synthesis of quinoxaline derivatives catalyzed by 1-<i>n</i>-butyl-3-methylimmidazolium tetrafluoroborate</b>

Abstract

The room temperature ionic liquid 1-n-butyl-3-methylimmidazolium tetrafluoroborate ([bmim]BF4) was used to promote the synthesis of quinoxaline derivatives under grinding condition. The yields were ranged in 86.0-95.1%. It was shown that the proposed method is fast, efficient and environmentally benign.
