involvement in the rearrangements is discussed. The kinetics of the isomerization reaction of the cyclometalated iridium(V) complex (5) to the iridium silylene [Cp*(PMe3)Ir(SiMes2)(H)][OTf] (6) were examined using NMR spectroscopic techniques. The primary kineticisotope effect (Si−H vs Si−D bond) for this process was determined to be 1.4 ± 0.1, implying a rate-limiting hydride migration from silicon to iridium
