CO₂ Binding and Splitting by Boron–Boron Multiple Bonds

Abstract

The room-temperature, ambient-pressure reactions of CO₂ with two species containing boron-boron multiple bonds led to the incorporation of either one or two CO₂ molecules. The structural characterization of a thermally unstable intermediate in one case indicates that an initial [2+2] cycloaddition is the key step in the reaction mechanism.
