Molecules, Vol. 25, Pages 352: Tunable Aryl Imidazolium Recyclable Ionic Liquid with Dual Brønsted-Lewis Acid as Green Catalyst for Friedel-Crafts Acylation and Thioesterification (Molecules)

Unique tunable aryl imidazolium ionic liquids successfully catalyzed Friedel–Crafts acylation and thioesterification in sealed tubes. These reactions can form a C−C bond and a C−S bond with high atom economy. Ionic liquids exhibited high activity and catalyzed essential reactions with good to excellent yields while retaining their catalytic activities for recycling.
