Sulfonic acid group functionalized imidazole based Brönsted acidic ionic liquids (BAILs) were synthesized and their activities were investigated in the hydration reaction of alkynes. The Hammett acidity order determined ...

In this study, a variety of imidazole/benzimidazole based sulfonic acid group functionalized Brönsted acidic ionic liquids (BAILs) were synthesized. Catalytic activities of BAILs were assessed using multi-component coupling ...
