Abstract A simple, efficient, and environmentally friendly ionic liquid mediated protocol for the synthesis of quinoxaline derivatives using carbonyl substrate and phenylenediamines has been described. A range of ionic liquids were synthesized, characterized via IR, 1H and 13C NMR and used as a solvent as well as catalyst for above protocol. The catalytic activities of ILs were evaluated and the relationship
摘要描述了一种使用羰基底物和
苯二胺合成
喹喔啉衍
生物的简单、高效且环境友好的
离子液体介导的方案。合成了一系列
离子液体,通过 IR、1H 和 13C NMR 进行表征,并用作上述协议的溶剂和催化剂。评价了
离子液体的催化活性,并讨论了催化活性与酸度之间的关系。还发现,在所有
离子液体中,[Bmim]CF3SO3 是上述礼仪中最有效、最环保、最便宜的溶剂和催化剂。由于
离子液体的环保性质和不使用单独的催化剂来推动反应的进行,该方法具有重要价值。
