The cyclic carbonate moiety finds many industrial applications because of its unique chemistry and properties. Phosgene, a highly toxic and corrosive reagent, has been utilized in the past to prepare low yields of fatty ester compounds (1) that contain a five-membered cyclic carbonate group. Herein, we show (CH3)4N HCO3, tetramethylammonium hydrogen carbonate (TMAHC), to react efficiently with ...
