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.

A method for preparing a compound of formula RSH where R represents an alkyl group, by gas-phase catalytic reaction of hydrogen sulfide with a compound of formula ROH, in the presence of a solid catalyst, according to which method the reaction is performed in the presence of a catalyst which includes one or several pure or mixed rare-earth oxide(s), one or several pure or mixed rare-earth sulfide(s), or one or several pure or mixed rare-earth oxysulfide(s). When the rare earth is lanthanum, the catalyst is a mixed oxide of lanthanum and of at least one metal selected from rare earths or not and when the rare earth is cerium, the catalyst is supported on an alumina.
