Recent Developments in Chemical Synthesis with Biocatalysts in Ionic Liquids.
Over the past decade, a variety of ionic liquids have emerged as greener solvents for use in the chemical manufacturing industries. Their unique properties have attracted the interest of chemists worldwide to employ them as replacement for conventional solvents in a diverse range of chemical transformations including biotransformations. Biocatalysts are often regarded as green catalysts compare...
متن کاملSynthesis and Sorption Analysis of Task-specific Fluorous Ionic Liquids
Six 1-alkyl-4-tridecafluorooctyl-1,2,4-triazolium triflimides 2a–f and 4-amino-1-tridecafluorooctyl-1,2,4-triazolium triflimide (4) were prepared from the respective iodides 1a–f (1a, 2a: n-propyl; 1b, 2b: n-butyl; 1c, 2c: n-hexyl; 1d, 2d: n-heptyl; 1e, 2e: n-octyl; 1f, 2f: n-decyl) and iodide 3 by ion metathesis. Compounds 2a and 4 are liquid at room temperature. Two liquid fluorous imidazoliu...
متن کاملThe use of supported acidic ionic liquids in organic synthesis.
Catalysts obtained by the immobilisation of acidic ionic liquids (ILs) on solid supports offer several advantages compared to the use of catalytically active ILs themselves. Immobilisation may result in an increase in the number of accessible active sites of the catalyst and a reduction of the amount of the IL required. The ionic liquid films on the carrier surfaces provide a homogeneous enviro...

متن کاملCarboxyl-functionalized task-specific ionic liquids for solubilizing metal oxides.
Imidazolium, pyridinium, pyrrolidinium, piperidinium, morpholinium, and quaternary ammonium bis(trifluoromethylsulfonyl)imide salts were functionalized with a carboxyl group. These ionic liquids are useful for the selective dissolution of metal oxides and hydroxides. Although these hydrophobic ionic liquids are immiscible with water at room temperature, several of them form a single phase with ...
