Al-based batteries are considered an attractive alternative to Li metal due the use of Al as anode with lower cost, reactivity and larger abundance compared Li. Despite aforementioned attributes, few electrolytes permit reversible electrodeposition at room temperature. Thus, for last 30 years, expensive imidazolium-based ionic liquids have dominated field. Even though extensive research has bee...

Catalytic activities of eight sulfonic acid group functionalized ionic liquids in water were compared for the hydrolysis of Sigmacell cellulose (DP ~ 450) in the 150-180°C temperature range by measuring total reducing sugar (TRS) and glucose produced. The catalytic activity of acidic ionic liquids with different cation types decreases in the order imidazolium > pyridinium > triethanol ammonium ...

Although there is now an increasing recognition of the existence of C -H -X (X = F, Cl, Br or I) hydrogen bonds in neutral organic molecules [1 , 2], there have been surprisingly few studies of C -H -X” interactions in organic salts. We have recently demonstrated the existence of extensive hydrogen bonding between aromatic C ~ H groups and halide ions, C -H X , within a series of imidazolium sa...

The 1,3-diaryl-imidazolium chlorides IPr.HCl (aryl = 2,6-diisopropylphenyl), IMes.HCl (aryl = 2,4,6-trimethylphenyl) and IXy.HCl (aryl = 2,6-dimethylphenyl), precursors to widely used N-heterocyclic carbene (NHC) ligands and catalysts, were prepared in high yields (81%, 69% and 89%, respectively) by the reaction of 1,4-diaryl-1, 4-diazabutadienes, paraformaldehyde and chlorotrimethylsilane in d...

Because of their great structural diversity and multitude of chemical properties, N-heterocyclic carbenes (NHCs) have been utilized in a variety of capacities. Most recently, NHCs have been utilized as carrier molecules for many transition metals in medicinal chemistry. Specifically, Ag(I)-NHCs have been investigated as potent antibacterial agents and chemotherapeutics and have shown great effi...

The imidazolium-based main-chain organic polymers are one of promising platforms in heterogeneous catalysis, the size and outer morphology of polymer particles are known to have important effects on their physical properties and catalytic applications, but main-chain ionic polymers usually generate amorphous or spherical particles. Herein, we presented a versatile and facile synthetic route for...

This paper describes the separation and detection of five inorganic anions (I - , BrO3 NO2 Br NO3 -) by capillary ion chromatography using 1-alkyl-3-methylimidazolium-coated columns UV at 210 nm. The salts imidazolium (IM) ions (C2-, C4-, C6-, C8-, C10-, C18-IMs) are a family ionic liquids were newly examined as permanent coating reagents on triacontyl (C30) -bonded silica reversed phase column...

Reactions of primary imidazolio-phosphides (“imidazolylidene-phosphinidenes”) with R2SnCl2 yield as main products spectroscopically detectable Lewis pairs which undergo base-induced dehydrochlorination in the presence excess dichlorostannane to afford zwitterionic chloride adducts distannylated imidazolio-phosphines. In contrast, reactions R3SnCl proceed under dismutation furnish mixtures conta...
