π-Olefin-iridium-komplexe : X. Einschiebung von diphenylacetylen in die methylen—iridium-bindung von bis(η4-cyclooctadien-μ-methylen-iridium)

Bis(η⁴-cyclooctadiene-μ-methyleneiridium) reacts with acetylenes to yield various products. In the case of diphenylacetylene two compounds have been isolated from the reaction mixture and identified as a $\text{1}\text{1}$ adduct containing a μ-η¹, η³-1,2-diphenylallyl ligand (X-ray structure analysis), and as 1,2,4,5-tetraphenylbenzene.
