Abstract: Methods of producing one or more trisubstituted lactone(s) comprising contacting a reaction mixture comprising one or more 2,2,3-trisubstituted epoxide(s) and one or more catalyst(s) with carbon monoxide. A catalyst may comprise a cationic Lewis acid and an anionic metal carbonyl. Methods may be regioselective and/or stereoselective. Trisubstituted lactones, which may be 3,3,4-trisubstituted β-lactones. Compositions comprising trisubstituted lactone(s). Polymers formed from trisubstituted lactone(s).
