The majority of industrially synthesized chemical compounds are prepared from a limited set of precursors, whose sources are ultimately fossil fuels. It would be beneficial to use a renewable resource, such as carbon dioxide, which is a non-toxic, abundant, and economical C1 synthetic unit. The coupling of carbon dioxide and olefins holds tremendous promise as one could envision the direct preparation of acrylates and carboxylic acids through this method. Currently, acrylic acid is produced via a two-stage oxidation of propylene. The production of acrylic acid directly from carbon dioxide and ethylene would represent a significant improvement due to the greater availability of ethylene and carbon dioxide versus propylene, the use of a renewable material (CO2) in the synthesis, and the replacement of the two-step oxygenation process currently being practiced. Accordingly, it is to these ends that the present invention is directed.
