Ionic solvent for Diels-Alder reactions and reactions catalyzed by transition metals

摘要

A process which employs the Diels-Alder reactions, or reactions catalysed by the transition metals, uses a non-aqueous, ionic solvent of formula Q+A-, which is liquid below 150 deg C. The Q+A- compound is prepared by reacting a trialkyloxonium of the anion with an amine in a hydrocarbon solvent.
