Co‐ and self‐metathesis of acyclic and unstrained sulfur‐containing ligands is catalyzed by the tungsten complex 1 . The catalyst is not poisoned by the sulfur‐containing substituents, possibly because of the shielding of the tungsten complex and the rigidity of its coordination. The intramolecular metathesis of diallyl sulfide catalyzed by 1 provides 2,5–dihydrothiophene in 80‐90% yield and ethylene.
