Dynamic tribochemical processes for dicationic ionic liquid containing a geminal imidazolium cation head group bridged by a poly(ethylene glycol) and a bis(trifluoromethylsulfonyl)imide anion were studied using time-resolved mechanically stimulated gas emission mass-spectrometry (MSGE-MS). In comparison with similar monocationic imidazolium ionic liquids with short alkyl or long polyether side ...

Dynamic tribochemical processes for dicationic ionic liquid containing a germinal 14 imidazolium cation head groups bridged by a poly(ethylene glycol) and 15 bis(trifluoromethylsulfonyl)imide anion were studied using time-resolved Mechanically 16 Stimulated Gas Emission Mass-Spectrometry (MSGE-MS). In comparison with similar 17 monocationic imidazolium ionic liquids with short alkylic or long p...

An atom-efficient, eco-friendly, solvent-free, high yielding, multicomponent green strategy to synthesize triazolo[1,2-a]indazole-triones derivatives by the one-pot condensation of aldehyde, dimedone, and phenyl urazole is presented. A series of different substituted aromatic aldehydes including either electron-withdrawing or electron-donating groups used in this reaction participated well and ...

in this paper, synthesis of the flower-like zinc oxide was performed using microwave assisted dicationic ionic liquid [mmp(im)2 ]br2 . the polycrystalline flower-like zinc oxide nanostructure was obtained when a suitable mole ratio (ionic liquid /zinc acetate) and short duration microwave was used. x-ray diffraction (xrd), scanning electron microscopy (sem), and photoluminescence (pl) spectra w...

in the present investigation, a novel adsorbent, ionic liquid modified magnetic nanoparticles (il-fe3o4), was successfully synthesized and characterized by ft-ir spectroscopy, thermogravimetric analysis (tga), xrd analysis, scanning electron microscopy (sem) and theory of brunauer, emmett, and teller (bet) for removal of reactive orange 122 (ro-122) from aqueous solutions. the effects of variou...

The novel dicationic metathesis catalyst [(RuCl2(H2ITapMe2)(=CH-2-(2-PrO)-C6H4))(2+) (OTf(-))2] (Ru-2, H2ITapMe2 = 1,3-bis(2',6'-dimethyl-4'-trimethylammoniumphenyl)-4,5-dihydroimidazol-2-ylidene, OTf(-) = CF3SO3 (-)) based on a dicationic N-heterocyclic carbene (NHC) ligand was prepared. The reactivity was tested in ring opening metathesis polymerization (ROMP) under biphasic conditions using ...

The present study, for the first time, presents a feasible protocol for the preparation of β-cyclodextrin/ imidazolium based dicationic ionic liquid, [βCD/Im](OTs)2, and its application as an efficient and eco-friendly microvessel and host ionic liquid system for the regioselective ring opening of the epoxides in water. No evidence for the formation of diol by-products or side reacti...

An efficient and convenient procedure for the hydrogen peroxide oxidation of primary alcohols to the carboxylic acids in aqueous media in regulated temperature-dependant; recyclable phase-separation catalytic system comprised of the PEG1000-based dicationic acidic ionic liquid and toluene under homogeneous conditions in good to excellent yield is reported.
