Mechanistic analysis of the reaction between elemental sulfur or selenium and 1,3-dialkylimidazolium acetate ionic liquids, in the absence of an external base or solvent, affords evidence for the equilibrium presence of carbene species in these ionic liqu

Page/Page column 5, (2010/10/19)
Process for preparing 1,3-disubstituted imidazolium salts of the formula I where R1 and R3 are each, independently of one another, an organic radical having from 1 to 20 carbon atoms, R2, R4 and R5 are each, independently of one another, an H atom or an organic radical having from 1 to 20 carbon atoms, X is the anion of a hydrogen acid having a pKa of at least 2 (measured at 25° C., 1 bar in water or dimethyl sulfoxide) and n is 1, 2 or 3, wherein a) an α-dicarbonyl compound, an aldehyde, an amine and the hydrogen acid of the anion X? are reacted with one another and b) the reaction is carried out in water, a solvent which is miscible with water or a mixture thereof.
