Abstract:
The Friedel-Crafts acylation of 2-methoxynaphthalene (2-MN) with acetic anhydride (AA) was carried out in the ionic liquid (IL) butylpyridinium tetrafluoroborate ([BPy]BF4) using phosphotungstic acid (H3PW12O40) as the catalyst. The [BPy]BF4-mediated 2-MN acylation displays good conversion and selectivity towards 1-acyl-2-methoxynaphthalene (1-AC-2-MN), with 70.4% conversion of 2-MN and 96.4% selectivity to 1-AC-2-MN obtained under the optimal conditions. Owing to the rearrangement of 1-AC-2-MN, 6-acyl-2-methoxynaphthalene (6-AC-2-MN) can be detected after 1 h of reaction time, with the highes

Silica matrices were prepared via acid catalysed sol-gel processing augmented with sonocatalysis. As silica precursors, a mixture of tetra-functionalized alkoxide (TMOS) and three-functionalized alkoxide methyl-trimethoxysilane (MTMS) were employed. Ionic liquid N-butyl-3-methylpyridinium tetrafluoroborate ([bmPy][BF4]), was used in various proportions, aiming to catalyse the sol-gel reactions, and to influence the mesoporous silica materials properties, serving as pore template.

Abstract:
Chiral ionic liquid derived from L-proline worked as an excellent organocatalyst for the enantioselective aldol reaction of aromatic aldehydes and acetone. The reaction was conducted in the presence of [BMIM][BF4] as reaction medium. The substrate scope of aldol reaction was successfully explored for various aromatic aldehydes under the mild conditions. The generated aldol products were separated by column chromatography with moderate to good yields as well as enantioselectivities. The main advantage of this catalytic method was that the catalyst and solvent could be recovered at the same time

A gate voltage, which can modulate the number of surface charge, can affect the ion concentration of Debye layer so as to change CDL. By measuring the ac impedance at various frequencies, we may establish an equivalent circuit model to estimate the CDL. We use the Nyquist plot fitting way to get CDL of 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIM-BF4). We found that CDL per area is 53μF/cm2. We also apply a
