A series of sulfur chelated dormant ruthenium olefin metathesis catalysts is presented. The catalysts prepared were shown to possess the uncommon cis-dichloro arrangement and were mostly inactive at room temperature. By systematically modifying the size of the substituent groups at the chelating sulfur atom, catalyst activity at different temperatures was significantly affected; more bulky substituents

Sulfur chelated ruthenium compounds and methods and compositions involving the same. A method may relate to subjecting an olefin to a metathesis reaction in the presence of a sulfur chelated ruthenium compound. A composition may relate to an olefin starting material dissolved in an organic solvent together with a sulfur chelated ruthenium compound.
