                                    This paper describes studies of the ring-closing metathesis of dialkyl sulfides and disulfides catalyzed by molybdenum and ruthenium alkylidenes. In general, the highest yields of ring-closed products were obtained using the molybdenum catalysts. Product yields were also strongly influenced by the substitution pattern about the double bonds: the yield of ring-closed products was found to decrease as the degree of substitution increased. These effects and other heteroatom effects are discussed. (C) 1997 Elsevier Science Ltd.
