carbon dioxide and ethylene oxide interact in the presence of palladium or rhodium catalysts to give (2′-hydroxyethyl)2-ethylidene-4,6-heptadienoate in a “one pot” reaction. When propylene oxide was used, two related isomeric esters with an additional methyl group in the alcohol part of the ester were obtained, in yields of up to 24%. Kinetic investigations suggest that the reaction occurs via the lactone
