Summary A study of the WCl6/(CH3)4Sn/CD2Cl2 initiated polymerization of otrimethylsilylphenylacetylene and 2-hexyne was completed. This study suggests that generated carbenes initiate the polymerization of mono and disubstituted acetylenes. Evidence was provided which clearly shows the formation ofthe initiating [W]=CH2 carbene complex and its immediate disappearance upon addition of both the 2-hexyne and o-trimethylsilylphenylacetylene. Under the reaction conditions used in the present study, no spectroscopic evidence of an initiating or propagating chain end or metallocyclobutene intermediate could be provided.
