MCM-41@ILLaCl4 under mild conditions. Merits of this meticulously designed protocol are the use of a novel supported ionic liquid catalyst, the easy work-up process, good to excellent yields, a short reaction time, and purification without column chromatography. Overall, the present protocol of synthesizing 2-oxazolidinones under cocatalyst- and solvent-free conditions using MCM-41@ILLaCl4 is promising for
合成了一种 MCM-41 负载的双咪唑鎓离子液体纳米催化剂,并发现其能够通过 CO2 与氮丙啶的可持续化学转化来合成 2-恶唑烷酮。结果表明,在催化量的固体催化剂MCM-41@ILLaCl4存在下,在温和条件下,一系列氮丙啶和CO2的环加成反应达到了最高效率。这种精心设计的方案的优点是使用新型负载离子液体催化剂、简单的后处理过程、良好至优异的收率、反应时间短以及无需柱色谱纯化。总体而言,目前使用 MCM-41@ILLaCl4 在无助催化剂和无溶剂条件下合成 2-恶唑烷酮的方案具有工业应用前景。
