A Homogeneous Mixture Composed of Vanadate, Acid, and TEMPO Functionalized Ionic Liquids for Alcohol Oxidation by H2O2 was written by Wang, Sa-Sa;Popovic, Zora;Wu, Hai-Hong;Liu, Ye. And the article was included in ChemCatChem in 2011.Electric Literature of C17H30BrN This article mentions the following:
Functionalized ionic liquids (ILs), such as N-(dodecyl)pyridinium vanadate (I), 1-(3-sulfopropyl)pyridinium tetrafluoroborate (II), and 2,2,6,6-tetramethyl-4-[1-oxo-3-(1-pyridinium-1-yl)propoxy]-1-piperidinyloxy tetrafluoroborate (III) were designed for a catalyst study and the synthesis of the target compounds was achieved by simple methods. A mixture of I, II and III in [Bpy]BF4 yielded compatible IL compositions (ILCs) as a homogeneous mixture, which proved to be an efficient catalytic system for oxidation of a wide range of alcs. using H2O2. With the aid of II or III the catalyst could easily recovered in [Bpy]BF4 (green chem. method) and reused for at least six runs without a loss in activity. UV/Vis spectroscopic anal. indicated that the role of 1-(3-sulfopropyl)pyridinium tetrafluoroborate was to promote the formation of the active peroxovanadium VV species, which is responsible for substrate activation, and the role of III was to oxidize the low-valent vanadium(II-IV) species to regenerate I. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Electric Literature of C17H30BrN).
1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Electric Literature of C17H30BrN
