Abstract

Real chemistry: Spectroscopic and crystallographic analyses confirm the chemical reaction of CO2 with carbene present in 1,3-dialkylimidazolium acetate ionic liquids and the supporting role of the acetate ion. When CO2 was bubbled through [C2mim][OAc], formation of the corresponding imidazolium carboxylate, [C2mim+-COO], could be observed.
