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.

Method for the preparation of thiocarbonates

A compound of formula IVa includes two or three Rto Rgroups which represent hydrogen, and the Rto Rgroups not being hydrogen represent a group CH—O—R, CH—O—C(═O)—R, or —CH—NRR, with Rto Rbeing a linear or branched alkyl group, alkoxy group, polyalkoxy group, or alkenyl group with at maximum 30 carbon atoms.

Thiocarbonate compounds

Process for the preparation of a compound with at least one five-membered cyclic monothiocarbonate group wherein a) a compound with at least one epoxy group is used as starting material b) the compound is reacted with phosgene or an alkyl chloroformate thus giving an adduct and c) the adduct is reacted with a compound comprising anionic sulfurthus obtaining the compound with at least one five-membered cyclic monothiocarbonate group.
