Abstract

Novel ionic liquid 1,3-disulfonic acid imidazolium hydrogen sulfate {[Dsim]HSO } ef?ciently catalyzes the synthesis of 1,2,4,5-tetrasubstituted imidazoles via the one-pot multi-component condensation of benzyl with aldehydes, primary amines and ammonium acetate at 90 8C under solvent-free conditions. Dual hydrogen-bond donors can be used to direct the assembly of this catalyst and the ef?ciency of it. 4
