Ionic Liquids, 3. Synthesis and Utilisation of Protic Imidazolium Salts in Homogeneous Catalysis

Abstract

Abstract Protonation of 1‐alkylimidazoles provides halogen‐free salts which act as ionic liquids and proton reservoir in proton‐ and metal‐assisted catalytic processes like dimerisation of methyl acrylate and ring closing metathesis, and lead to significant improvements both in activity and selectivity.
