L-proline promoted Ullmann-type reaction of vinyl bromides with imidazoles in ionic liquids.

چکیده
The Ullmann-type coupling reaction of vinyl bromides and imidazoles in ILs at 90-110 degrees C gave the corresponding N-vinylimidazoles in good to excellent yields by using L-proline as the ligand; the double bond geometry of the vinyl bromides was retained under the reaction conditions.

Chemoenzymatic synthesis and biological evaluation of enantiomerically enriched 1-(β-hydroxypropyl)imidazolium- and triazolium-based ionic liquids
Racemic 1-(β-hydroxypropyl)azoles were prepared by solvent-free direct regioselective ring opening of 1,2-propylene oxide with imidazole or 1,2,4-triazole. Lipase-catalyzed transesterification of alcohols with vinyl acetate resulted in kinetic enantiomers resolution. Separated (S)-enantiomers of (+)-1-(1H-imidazol-1-yl)propan-2-ol and (+)-1-(1H-1,2,4-triazol-1-yl)propan-2-ol were quaternized wi...

متن کاملH-imidazolium Acidic Ionic Liquids as Efficient Catalysts in the Synthesis of Xanthenes under Solvent-Free Conditions
Bifunctional acidic ionic liquids, having both H-imidazolium and -SO3H groups as cation moieties (H-BFAILs) and CF3SO3- as anion, were synthesized in high yields. These H-BFAILs showed significant hydrophilic properties, lower acidity and higher thermal stability relative to common ionic liquids, due to their unique structures. The (propyl or butyl-3-sulfonic) imidazolium trifluoromethane sulfo...
