Complexes featuring the Cp*Ir motif have been shown to activate C-H bonds. However, the utilization of these complexes for C-H functionalization has remained a challenge. A series of complexes featuring this ligand framework have been synthesized and their propensity for C-H activation via H/D exchange in different solvents (triflouroacetic acid-d1, acetic acid-d4 and methanol-d4) was examined by a GC-MS assay. Isotope effect and initial rates studies have revealed a possible change in mechanism when varying the solvent. Further, it has been demonstrated that Cp*Ir complexes can be utilized for catalytic C-H functionalization reactions and the utilization of these complexes for catalytic C-C bond forming reactions will be described.
