Abstract
This disclosure provides for routes of synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, including catalytic methods. For example, there is provided a process for producing an α,β-unsaturated carboxylic acid or a salt thereof, the process comprising: (1) contacting in any order, a group 8-11 transition metal precursor, an olefin, carbon dioxide, a diluent, and a polyaromatic resin with associated metal cations to provide a reaction mixture; and (2) applying conditions to the reaction 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.
