| Zusammenfassung: | A combination of electrospray ionization MS/MS techniques, isotopic labeling experiments in the gas-phase and solution, and ab initio calculations is used to study the C−H activation reactions of [Cp*Ir(PMe3)(CH3)]+ and [CpIr(PMe3)(CH3)]+. The reaction in the gas phase was found to proceed through a Cp or [Cp*Ir(η2-CH2PMe2)]+ intermediate. Quantitative collision-induced dissociation (CID) threshold measurements were used along with general models for ion−molecule reactions to construct potential energy diagrams which rationalize the gas-phase results. The comparison between the two complexes, and between the reactions in the gas phase and in solution, suggests that the reaction through the intermediacy of a metallaphosphacyclopropane could be favored over the conventional (and simpler) oxidative addition/reductive elimination mechanism when the Ir(III) complex is rendered more electron deficient. |
