(η5-Indenyl)rhodium(I) complexes of the general composition [(η5-C9H7)Rh(=CPh2)(L)] (L = SbiPr3 (6), PiPr3 (7), PPh3 (8), P/PrPh2 (9), PiPr2Ph (10)) were prepared from the square-planar precursors frans-[RhCl(=CPh2)(L)2] (1-5) and C9H7K in THF. Treatment of 6-10 with carbon monoxide resulted in an unusual migratory insertion of the carbene ligand into one of the C-H bonds of the five-membered ring of the indenyl unit to give the compounds [{η5-C9H6(CHPh2)}Rh(CO)(L)] (12-16) in 78-87% yield. The X-ray crystal structure analyses of 6 and 13 revealed that in both complexes the slip distortion from a η5 to a η3 coordination mode of the indenyl ligand is nearly the same, independent of the bulky CHPh2 group in the ring-substituted species.
