Iridium indenyl compounds

Carbon monoxide insertion into an iridium-methyl bond has been reported for an >j -indenyl compound of iridium(III), Ir(/7 -C9H7)Me2(PMe3)(CO)2- In the presence of one equivalent of trimethylamine oxide, used as a carbon monoxide scavenger, carbon monoxide insertion occurs with a simultaneous increase in the hapticity of the indenyl ligand ... 

Tris(boryl) complexes have been shown to have a central role in the iridium-catalyzed borylation of arenes [136,137]. The syntheses of the half-sandwich iridium(III) systems ( 6-toluene)Ir(Bcat)3, 9.34, and rf-mesitylene)Ir(Bcat)3, 9.35, were reported by Marder and co-workers in 1993, by exploiting the reaction of ( 5-Ind)Ir(cod) with excess HBcat using the arene as a solvent. The organic products of the reactions were found not only to include species resulting from the hydroboration or hydrogenation of the cod or indenyl ligands, but also compounds derived from borylation...
