A Bifunctional Tungstate Catalyst for Chemical Fixation of CO₂ at Atmospheric Pressure

Abstract

No pressure: A simple monomeric tungstate, [WO4]2−, serves as a highly efficient homogeneous catalyst for various transformations of CO2 at atmospheric pressure. The tungsten-oxo moiety activates CO2 and the substrate simultaneously. The catalyst system is high yielding and applicable to a wide range of substrates such as amines (see scheme), 2-aminobenzonitriles, and propargylic alcohols.
