Bifunctional Tungstate Catalyst for Chemical Fixation of CO2 at Atmospheric Pressure

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

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.

Interesting use of diaminobenzene as CO acceptor and H2 donor.
