Abstract

Raman and NMR spectroscopies show that CS₂ and OCS react spontaneously with 1-butyl-3-methylimidazolium acetate [C₄mim] [Ac] in the liquid phase. The formation of [C₄mim] CO₂, [C₄mim] COS, CH₃COS⁻ and gaseous CO₂ and OCS in both systems demonstrates that the anion plays an unexpected role not observed in the CO₂–[C₄mim] [Ac] reaction.
