In FY2014, we initiated the investigation of the incorporation of carbon dioxide into C-C unsaturated bonds for the synthesis of value-added chemicals. Various N-heterocyclic carbene supported Fe, Ni, Cu, and Zn complexes have been synthesized. These catalysts have been screened in the model reaction of diphenylacetylene with carbon dioxide. After analysis of the reaction mixtures of initial trials, we have identified the formation of the expected product. The structure of this product was also confirmed by characterization of the isolated pure compound. We are now working on the systematic screening of metal slats, ligands, solvents, additives, reaction temperature, and other reaction factors to improve the yield of the current reaction. The preparation and isolation of some reaction intermediates from stoichiometric reactions of metal complexes are also underway.
We also got some preliminary results of the reaction of alkenes with carbon dioxide and started to optimize the reaction conditions of this transformation.
