Reaction of [(cod)IrI]₂ (cod = 1,5-cyclooctadiene) with methyllithium in the presence of diphenylacetylene (tolane) yields a (cod)Ir complex (3) with a 1-benzyl-2.3-diphenyl-7-methyl-indenyl ligand which is formed by a novel cyclization of two tolane units with participation of a methyl group. The compound was characterized by spectroscopic methods and by X-ray diffraction analysis.
