Oxidative Addition of Halo(methyl)silanes to an In Situ Generated Ir(I) Complex and β-Hydride Elimination Reaction of the Resulting (Methylsilyl)iridium Complexes

Halomethylsilanes (MeSiCl3, Me3SiI, Me2SiCl2, Me3SiCl, and Me3SiBr) undergo oxidative addition to IrH(pipr3)2 in situ generated from IrH5(pipr3)2 and two equivalent neohexene to form halo(organosilyl)iridium(III) complexes. In addition, the resulting (methylsilyl)iridium complexes undergo β-hydride elimination reactions leading to the formation of dihydroiridium species.
