Abstract

Provided is a process for the preparation of a compound with at least one five-membered cyclic monothiocarbonate group. A compound C1 with at least one halohydrin group is used as starting material. Compound C1 is reacted with phosgene or an alkyl chloroformate to give an adduct C2. The adduct C2 is reacted with a compound that includes anionic sulfur to obtain the compound with at least one five-membered cyclic monothiocarbonate group.
