The liquid structure of aqueous solutions of five different imidazolium based gemini dicationic ionic liquids 1,n-bis(3-methylimidazolium-1-yl) alkane bromide (n being the length of the spacer alkyl chain), with propyl, pentyl, octyl, decyl and hexadecyl spacer chains has been studied using atomistic molecular dynamics simulations. While solutions with propyl and pentyl spacers are homogeneous,...

In this study, simple ionic liquid-assisted preparation of SnO microflowers with nanosheet subunitsunder reflux condition without calcination were described. Samples were synthesized using 1-pentyl-3-methylimidazolium bromide, [pmim]Br, as an ionic liquid in different molar ratio, sodium hydroxideand Tin(II) chloride. The results show that SnO with high purity and uniform size...

X-ray absorption spectroscopy (XAS) has been used to unveil the bromide ion local coordination structure in 1-alkyl-3-methylimidazolium bromide [C(n)mim]Br ionic liquids (ILs) with different alkyl chains. The XAS spectrum of 1-ethyl-3-methylimidazolium bromide has been found to be different from those of the other members of the series, from the butyl to the decyl derivatives, that have all ide...

In this paper, we report on the crystal structure of salt 1-(4-bromo-2,3,5,6-tetrafluorophenyl)-3-(3-phenylbenzyl)-4-methylimidazolium bromide, 3, synthesized by sequential nucleophilic attack 4-methylimidazole bromopentafluorobenzene and then 3-phenylbenzyl bromide. The was characterized 1H, 13C, 19F NMR spectroscopy mass spectrometry.

Six different bromide salts - tetraethylammonium bromide ([N2,2,2,2]Br, Br), 1-ethyl-1-methylpiperidinium bromide ([C2MPip]Br, Br), 1-ethyl-1-methylpyrrolidinium bromide ([C2MPyrr]Br, Br), 1-ethyl-3-methylimidazolium bromide ([C2MIm]Br, Br), 1-ethylpyridinium bromide ([C2Py]Br, Br), and 1-(2-hydroxyethyl)pyridinium bromide ([C2OHPy]Br, Br) - were studied in regards to their capacity to form pol...

The structure-directing effect of amine has been observed in the ionothermal synthesis of aluminophosphate molecular sieves in 1-butyl-3-methylimidazolium bromide ionic liquid. The seven different amines we tested have an influence on the crystallization dynamics and the final product, leading to the formation of pure AFI and ATV structures.

The microwave-assisted three-component reactions of 3,5-bis(E)-arylmethylidene]tetrahydro-4(1H)-pyridinones, acenaphthenequinone and cyclic α-amino acids in an ionic liquid, 1-butyl-3-methylimidazolium bromide, occurred through a domino sequence affording structurally intriguing diazaheptacyclic cage-like compounds in excellent yields.
