Four new amino-functionalized pyrazolium ionic liquids, I [R = Me, Et; n = 1, 2] were firstly synthesized in simple reaction steps with cheap raw materials. Ionic liquids I would catalyze the coupling reaction of carbon dioxide with propyleneoxide under optimal reaction conditions, 110 °C, 1.5 MPa carbon dioxide initial pressure as well as 1.0 mol% catalyst amount for 4.0 h, with propylene carbonate yield over 94%. The reaction temperature was decreased by 10-20 °C as compared with other single-component ionic liquids and at the same time, carbon dioxide initial pressure was not increased to keep 1.5 MPa. The recyclability and suitability of amino-functionalized pyrazolium ionic liquids were explored and catalytic mechanism was investigated by d. functional theory. Moreover, the influence of weak interactions on reaction was analyzed by atoms in mols. and non-covalent interactions. As compared with other reported ionic liquids, the reaction condition catalyzed by ionic liquid I [R = Et, n = 2] was more benign with comparable product yield. More importantly, there was good balance among various reaction conditions without sacrificing one to ensure others. In addition to this study using 1-Methylpyrazole, there are many other studies that have used 1-Methylpyrazole(cas: 930-36-9Recommanded Product: 930-36-9) was used in this study.
1-Methylpyrazole(cas: 930-36-9) belongs to pyrazoles. Pyrazole derivatives have been reported to exhibit a wide range of applications in medicinal chemistry and pharmacology. A large number of drugs incorporating pyrazole structure have been utilized as partial agonists for nicotinic acid receptors, antidepressants, antimicrobial agents, antiviral agents, and antifungal agents solely or along with the combination of other structural motifs.Recommanded Product: 930-36-9
