H-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...

متن کاملRoom Temperature Synthesis of Mequinol by Using Ionic Liquids as Homogeneous Recyclable Catalysts
For the synthesis of Mequinol (4-methoxy phenol), two acidic ionic liquids based on imidazolium cation (BMSIL and IMSIL) synthesized and characterized by FT-IR, 1H NMR, and CHNS analyses. Tan, the Baeyer–Villiger oxidation of para-anisaldehyde was studied with these ionic liquids, as the catalysts. The results showed that the BMSIL with more Brønsted acidic functions had higher c...
متن کاملIonic liquids as efficient catalysts for synthesis of phosphorylated dialkyl succinates containing phthalazin-1-one moieties
Ionic liquids such as 1,3-dialkylimidazolium salts make excellent catalysts and solvents for synthesis of dialkyl 2-(dialkoxyphosphoryl)-3-(1-oxo-1-H-phthalazin-2-yl)succinates from 2H-phthalazin-1-one, dialkyl acetylenedicarboxylates, and trialkyl phosphites. Under similar conditions, triphenyl phosphite led to dialkyl 2-(diphenoxyphosphoryl)-3-(1-oxo-1-H-phthalazin-2-yl)succinates. The ionic ...
