Ionic liquid-functionalized SBA-15 mesoporous material: efficient heterogeneous catalyst in versatile organic reactions was written by Xu, Li-Wen;Yang, Ming-Song;Jiang, Jian-Xiong;Qiu, Hua-Yu;Lai, Guo-Qiao. And the article was included in Central European Journal of Chemistry in 2007.Reference of 79917-89-8 This article mentions the following:
Ionic liquid-functionalized mesoporous materials exhibited high catalytic activity in versatile organic reactions, such as cycloaddition of carbon dioxide (CO2) with epoxide, aza-Michael addition of amines to α,β-unsaturated carbonyl compounds, and the Biginelli reaction of aldehyde, Et acetoacetate and urea. Recycling of the catalyst in these reactions could be carried out and the catalyst used at least five times without significant loss in activity. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Reference of 79917-89-8).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Reference of 79917-89-8
