Hydrogenation of Carbon Dioxide is Promoted by a Task‐Specific Ionic Liquid

Abstract

A basic hydrogenation catalyst: The combination of a basic ionic liquid (IL) and a supported ruthenium complex catalyzes the hydrogenation of CO2 with satisfactory activity and selectivity (see scheme). The resulting formic acid is easily collected and the ionic liquid and catalyst can be reused directly after an easy separation step.
