New catalytic materials, based on palladium immobilized in ionic liquid supported on alginate, were elaborated. Alginate was associated with gelatin for the immobilization of ionic liquids (ILs) and the binding of palladium. These catalytic materials were designed in the form of highly porous monoliths (HPMs), in order to be used in a column reactor. The catalytic materials were tested for the ...

Highly active rhodium catalysts have been prepared by immobilization of an ionic liquid film on carbon nanotubes functionalized with imidazolium-based ionic moieties.

Amine precursors such as NH-Boc (5) and NH-formyl (6) protected glycines were grafted by esterification on the hy-droxylated arms of 1-(2-hydroxyethyl)-3-methylimidazolium hexafluorophosphates 4h or tetrafluoroborates 4t. The Boc cleav-age was then realized at room temperature by successively treating acetonitrile solutions of the carbamates 7h or 7t with methanol and acetyl chloride (2 equival...

Due to the protection of ionic liquid polymer thin film, the long-term operation stability of carbon nanotube-supported platinum nanoparticles for methanol electrooxidation has been improved.

Hollow fiber supported ionic liquid membranes (SILMs) were tested using the bubble point method to investigate potential failure modes, including the maximum transmembrane pressure before loss of the ionic liquid from the support. Porous hollow fiber supports were fabricated with different pore morphologies using Matrimid(®) and Torlon(®) as the polymeric material and 1-hexyl-3-methylimidalzoli...

A direct and an efficient conversion of a wide range of primary, secondary even tertiary alcohols to the corresponding iodides have been achieved under ionic liquid conditions. The method involves preparation of ionic liquid-based iminium chloride intermediate from DMF-like ionic liquid then stirring it with alcohol in present of sodium iodide. The higher yields of alkyl iodides were obtained w...

The Magnetically recoverable Fe3O4 nanoparticle and the supported brønsted acidic ionic liquid 1-methyl-3-(3-trimethoxysilylpropyl) imidazolium hydrogen sulfate (Fe3O4-IL-HSO4) were synthesized and used as efficient magnetic catalysts for the regioselective thiocyanation of aromatic and heteroaromatic compounds at room temperature in Water: Ethanol. This procedure provided the target thiocyanat...

A variety of alcohols readily add to 3,4-dihydro-2H-pyran under solvent free conditions in the presence of catalytic amount of acidic ionic liquid [Et3N(CH2)4SO3H][OTs] to afford the corresponding tetrahydropyranyl ethers in good to excellent yields at room temperature. The use of this procedure allows easy separation of the desired products ...

We describe a convenient route to the alignment of cyclic peptide nanotubes (CPNs). The key lies in the use of nanostructured ionic liquids. An ionic liquid supported membrane with orientated domains is demonstrated, leading to aligned CPNs within a solid membrane.
