Abstract:
Disclosed is a continuous process for producing α,β-unsaturated carboxylic acids or salts thereof, comprising: 1) in a first stage, contacting (a) a transition metal precursor compound comprising at least one first ligand, (b) optionally, at least one second ligand, (c) an olefin, (d) carbon dioxide (CO 2 ), and (e) a diluent to form a first composition; 2) in a second stage, contacting a polyanionic solid with the first composition to form a second composition; and 3) in a third stage, (a) contacting the second composition with a polar solvent to release a metal salt of an α,β-unsaturated carboxylic acid and form a reacted solid. Methods of regenerating the polyanionic solid are described.

Claim (Index 11):
A continuous process according to  claim 1 , wherein the polyanionic solid comprises an organic base moiety immobilized on a solid support comprises structural units having the general formula (I):\n SS-[A] x -L-B\u2003\u2003(I); wherein SS is a solid support, A is an anchor moiety, L is a direct bond or linking moiety, and B is an organic base moiety, and x is 0 to 3; and wherein the organic base moiety B has the general formula:\n [\u2014CR 1 R 2 \u2014O] \u2212 ,[\u2014CR 1 R 2 \u2014S] \u2212 ,[\u2014CR 1 R 2 \u2014NR 3 ] \u2212 , or [\u2014CR 1 R 2 \u2014PR 3 ] \u2212 , \n wherein each of R 1  and R 2 , independently or together, are selected from H or an unbranched or branched, acyclic or cyclic, C 1 -C 12  hydrocarbyl residue; and R 3  is selected independently from hydrogen or a substituted or an unsubstituted C 1 -C 12  hydrocarbyl.
