Abstract
The titanium derivatives CpCp′TiX2(Cp η5-C5H5; Cp′=η5-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.Keywords
