The reaction of Cp*Ir III phosphoramidate (Cp* = pentamethylcyclopentadienyl) complexes with a monohydroborane (HBR 2 ; R = cyclohexyl or mesityl) generates cyclometalated Cp*Ir III complexes following two sequential intramolecular B–H and C(sp 3 )–H bond‐activation events. Preliminary mechanistic inquiry suggests that boron stabilization provided by the hemilabile phosphoramidate ligand provides a δ ‐B–H ··· [Ir] coordinated intermediate, which succumbs to borane‐induced C(sp 3 )–H bond activation.
