The titanium derivatives CpCp⠲TiX2(Cp η<sup>5</sup>-C5H5; Cp⠲=η<sup>5</sup>-C5Me5; X = Me, Ph, or CO) have been synthesized and the reaction of CpCp⠲Ti(CO)2 with diphenylacetylene and trimethylphosphine affords the unsaturated (alkyne)titanium(II) complex CpCp⠲Ti(C2Ph2) which readily adds carbon dioxide to give the metallacyclic compound [graphic omitted] via carbon-carbon bond formation.
