Synthesis and Reactivity of Early−Late Heterobimetallic Hydrides of Group 4 Metals and Iridium Supported by Mono(η5-C5Me5) Ancillary Ligands: Bimetallic Carbon−Hydrogen Bond Activation
Group 4 metal−iridium early−late heterobimetallic (ELHB) hydrido complexes supported by pentamethylcyclopentadienyl ligands (Cp*MCl2)(Cp*Ir)(μ-H)3 (1: M = Ti, Zr, Hf) have been synthesized. The hydrocarbyl complexes {Cp*M(CH2SiMe3)2}(Cp*Ir)(μ-H)3 (3: M = Zr, Hf) derived from 1 displayed cooperative reactivity in carbon−hydrogen bond activation of methoxyarenes and pyridines.
