Abstract

Highly unsaturated mono(N-heterocyclic carbene) Ir(iii) systems have been targeted via ligand abstraction protocols. Hydrogenation of Ir(IPr)(cod)Cl (1a) leads to the formation of the highly reactive (fluxional) trimer [Ir(IPr)(H)₂Cl]₃, while the related IMes system undergoes further C-H bond activation. Chloride abstraction from 1aprior to hydrogenation allows access to sources of the 12-electron [Ir(IPr)(H)₂]⁺ fragment, which, in the absence of a suitable donor, dimerizes to give [{Ir(IPr)(H)(μ-H)}₂]²⁺.
