A series of betaine-based salts containing quaternary ammonium ion and carboxylic acid group were synthesized by direct protonation of anhydrous betaine using different BrΓΈnsted acids. The catalytic activity of these salts for the synthesis of cyclic carbonates via cycloaddition reaction of CO 2 wit
