  Methods of producing α,β-unsaturated carboxylic acid salt are described. A method can include reacting an alkene and carbon dioxide with a composition that includes a carboxylation catalyst, an organic base that is solubilized in the composition, and an inorganic base that is not solubilized in the composition, under reaction conditions suitable to produce an inorganic base salt of an α,β-unsaturated carboxylic acid. The organic base can have a first pKa and the inorganic base has a second pKa that is greater than the first pKa.
