• As a promoter in the regioselective direct arylation of azoles (1-methylpyrazole, oxazole, and thiazole) with aryl bromides in presence of palladium acetate catalyst.
• As an ionic liquid to dissolve cellulose in the presence of DMSO co-solvent.
• As an activator in the synthesis of disubstituted alkynes through copper-free Sonogashira coupling reaction.
