Abstract:
This disclosure provides for routes of synthesis of α,β-unsaturated carboxylic acids and their salts, including acrylic acid. For example, disclosed is a process for producing an α,β-unsaturated carboxylic acid or its salt, comprising: (1) contacting a group 8-11 transition metal precursor, an olefin, carbon dioxide, a diluent, and a sulfur oxoacid anion-substituted polyaromatic resin or a phosphorus oxoacid anion-substituted polyaromatic resin with associated metal cations to provide a mixture; and (2) applying reaction conditions to the mixture suitable to produce the α,β-unsaturated carboxylic acid or a salt thereof. Methods of regenerating the polyaromatic resin with associated metal cations are described.

Claim (Index 1):
A process for forming an \u03b1,\u03b2-unsaturated carboxylic acid or a salt thereof, the process comprising:\n a) contacting in any order\n 1) a transition metal precursor comprising at least one first ligand; \n 2) optionally, at least one second ligand; \n 3) an olefin; \n 4) carbon dioxide (CO 2 ); \n 5) a diluent; and \n 6) a sulfur oxoacid anion-substituted polyaromatic resin or a phosphorus oxoacid anion-substituted polyaromatic resin, wherein the polyaromatic resin further comprises associated metal cations, to provide a reaction mixture; and \n b) applying reaction conditions to the reaction mixture suitable to form the \u03b1,\u03b2-unsaturated carboxylic acid or the salt thereof.
