This dissertation describes the synthesis and reactions of ruthenium- and tungsten-thioalkyne complexes. The alkyne, MeSC=CSMe, initially reacts with Cp(PMe {sub 3}){sub 2}RuCl to form the sulfur-bound alkyne complex {l brace} Cp(PMe {sub 3}){sub 2}Ru (S (Me) C=CSMe){r brace}{sup +}, which readily rearranges to the vinylidene (Cp (PMe {sub 3}){sub 2} Ru=C=C (SMe){sub 2}){sup +}. This vinylidene complex is either readily reduced with a variety of charged nucleophiles to give the thioacetylide Cp (PMe{sub 3}){sub 2} Ru-C=CSMe and MeSSMe; or reacts with electrophiles H{sup +} and MeS{sup +} (E) to give three-member metallacyclic complexes {l brace}Cp (PMe {sub 3}){sub 2} Ru(S (Me) C=C= (E) SMe){r brace}{sup +2}.
