Efficient and convenient oxidation of sulfides to sulfones using H2O2 catalyzed by V2O5 in ionic liquid [C12mim][HSO4] was written by Hu, Yu-Lin;Liu, Xiao-Bing;Fang, Dong. And the article was included in Catalysis Science & Technology in 2014.Electric Literature of C18H31F6N3O4S2 This article mentions the following:
A simple, efficient, and eco-friendly procedure for the oxidation of sulfides to sulfones using H2O2 catalyzed by V2O5 in ionic liquid [C12mim][HSO4] has been developed. This atom-economical protocol affords the target products in good to high yields. The products can be separated by a simple extraction with organic solvent, and the catalytic system can be recycled and reused without loss of catalytic activity. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Electric Literature of C18H31F6N3O4S2).
3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Electric Literature of C18H31F6N3O4S2
