Abstract

A series of task-specific ionic liquids (ILs) such as mono-, dicationic, and polymer-supported ILs were synthesized. These ILs were applied as multitasking organocatalysts for transformations of carbon dioxide into valuable chemicals through a range of reactions, including (i) cycloaddition reactions of CO₂/CS₂ with epoxides to form cyclic carbonates and 1,3-oxathiolane-2-thiones, (ii) transesterification of cyclic carbonates with methanol to form dimethyl carbonate, and (iii) synthesis of quinazoline-2,4(1 H,3 H)-diones and quinazoline-2,4(1 H,3 H)-dithiones from 2-aminobenzonitriles and CO₂/CS₂. The developed methodology is transition-metal free, solvent free, and additive free. Remarkably, the developed ILs were recyclable in up to seven consecutive cycles; thus, making this protocol green and cost effective.
