Abstract
Terminal acetylenes RCCH Are transformed catalytically in to matathesis product in to methathesis products RCCR and C2H2 on the carbine complex [W(CBut)(OBut)3], a polymerization of the alkyne; in the case of sterically hindered ButCCH, a stoichiometric reaction is observed, by which a dinuclear compound µ-C2H2[W(OBut)3]21 and the deporotiotungstenacyclobutadiene [WC3(But)2(OBut)2]2 are formed.Keywords
