title: Intermolecular C-H Bond Activation by a Cationic Iridium(III) Dichloride Phenanthroline Complex.
abstract: It is demonstrated that a cationic iridium(III) dichloride phenanthroline complex is capable of C-H activation and H/D exchange. It can cleave benzylic and unactivated secondary C-H bonds, but exhibits unique selectivity when compared to similar systems that have been studied in the condensed phase. Gas-phase rate constants and kinetic isotope effects are reported for a variety of substrates and the analysis is supported by DFT calculations at the M06/QZVP level.
