Abstract
A process for the preparation of organic compounds or polymers containing one or more sulphur atoms and including one or more double bonds in a hydrocarbon chain is described. An acyclic sulphur-containing olefin or an unsaturated sulphur-containing cyclic hydrocarbon undergoes a self metathesis reaction or a cross metathesis reaction with a non-sulphur-containing acyclic olefin or a non-sulphur-containing unsaturated cyclic hydrocarbon to produce novel olefins, novel dienes, and/or olefinic polymers containing one or more sulphur atoms.
