Catch me if you can: Tetramethylammonium salts bearing a β-amino acid anion (TMAAs) are synthesized through Michael addition reactions of amines with methyl acrylate, subsequent hydrolysis, and neutralization with aqueous tetramethylammonium hydroxide. These TMAAs interact with CO2 in a 1:1 mode in ethylene glycol, which forms hydroxyethylcarbonate species. The driving force for the 1:1 bonding appears to be the intramolecular hydrogen bonding network exerted through the carboxylate group.
