Task Specific Ionic Liquid

2-Hydroxyethylammonium formate acts as a task-specific ionic liquid (TSIL) for the Knoevenagel condensation of carbonyl compounds with rhodanine to afford arylalkylidene rhodanines under solvent-free conditions and in good-to-excellent yields. Additionally, compared with those in organic solvents, the yields obtained in the presence of our ionic liquid (IL) were significantly increased. The detailed mechanism of the catalytic effect of TSIL is also reported for the first time.

Task Specific Ionic Liquid

A sulfonic-acid-functionalized ionic liquid is used as a Brønsted acid catalyst for the efficient synthesis of indole derivatives in good-to-high yields at room temperature under solvent-free conditions. The catalyst can be reused for ten consecutive runs without significant loss of activity.
