Abstract

A process synthesizes a compound with at least one alkylene group and at least one thiol or thiolate group. The process involves reacting a compound with at least one five-membered cyclic monothiocarbonate group with a starter selected from a compound with at least one thiol group, from a compound with at least one hydroxy group, or from a basic inorganic composed; to obtain a compound with at least one alkylene group and at least one thiol or thiolate group and carbon dioxide.
