Lithium chloride-imidazolium chloride melts for the coupling reactions of propylene oxide and CO2 was written by Nguyen, Ly Vinh;Lee, Bora;Nguyen, Dinh Quan;Kang, Min-Jung;Lee, Hyunjoo;Ryu, Seol;Kim, Hoon Sik;Lee, Je Seung. And the article was included in Bulletin of the Korean Chemical Society in 2008.Formula: C7H13ClN2 This article mentions the following:
A series of lithium chloride-imidazolium chloride (LiCl-[imidazolium]Cl) melts were prepared and their catalytic activities were evaluated for the coupling reactions of propylene oxide and CO2. At the constant mole of LiCl, the catalytic activities of LiCl-[imidazolium]Cl melts increased with increasing molar ratio of [imidazolium]Cl/LiCl up to 2, but thereafter decreased rapidly. The variation of alkyl groups on the imidazolium ring showed a negligible effect on the catalytic activity, but the number of alkyl groups present on the imidazolium cation exerts a pronounced effect. Catalysis and electrospray ionization tandem mass spectral anal. results of LiCl-[imidazolium]Cl melts imply that the activity of the melt is strongly related to the amount of LiCl2– generated from the melt. In the experiment, the researchers used many compounds, for example, 1-ethyl-2,3-dimethylimidazolium chloride (cas: 92507-97-6Formula: C7H13ClN2).
1-ethyl-2,3-dimethylimidazolium chloride (cas: 92507-97-6) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Formula: C7H13ClN2
