Procedure

20 g of the methyl epoxypropionate were mixed with 20 g of tert-butyl methyl ether and 1 g of tetrabutylammonium bromide. The homogeneous mixture was transferred to a 100 ml pressurized reactor and carboxylated for 4 days at 40° C. and a CO2 pressure of 20 bar. Following carboxylation, a two-phase system was obtained; the upper phase consisted of tert-butyl methyl ether, and the lower phase consisted of 4-methoxycarbonyl-2-oxo-1,3-dioxolane (purity 94% (GC), yield 94%).
