In this method, a novel Br?nsted acidic ionic liquid silica-supported pyridinium sulfonic acid thiocyanate {SiO2@[Pyridine-SO3H]SCN} and sulfonic acid-functionalized pyridinium chloride {[PSA]Cl} were easily synthesized and character
1-methyl-3-(2-(Sulfooxy)Ethyl)-1H-imidazol-3-ium thiocyanate as a novel, green, and efficient bronsted acidic ionic liquid-promoted regioselective thiocyanation of aromatic and heteroaromatic compounds at room temperature

An efficient and simple method for the preparation of 1-methyl-3-(2- (sulfooxy)ethyl)-1H-imidazol-3-ium thiocyanate ([Msei]SCN) as a Bronsted acidic ionic liquid (BAIL) is described, and it is used in the highly efficient regioselective thiocyanation of aromatic and heteroaromatic compounds via a green and simple protocol. [Msei]SCN as a novel IL and thiocyanation agent, H2O2 as a mild and environmentally friendly oxidant, and H2O:ethanol(1:4) as a solvent were used. This procedure provided the target thiocyanates in high yield and very short reaction time. [Supplementary materials are available for this article.

experimental part, p. 34 - 38 (2012/08/28)
Silica vanadic acid (in which vanadium oxytrichloride has been supported on silica) is applied as an efficient, reusable and heterogeneous catalyst for the thiocyanation of heterocycles, substituted anilines (electron-rich and electron-deficient) and N-su
