C–H Activation of 2,4,6-Triphenylphosphinine: Synthesis and Characterization of the First Homoleptic Phosphinine–Iridium(III) Complex <i>fac</i>-[Ir(C^P)<sub>3</sub>]

Access to homoleptic phosphinine-based coordination compounds of d<sup>6</sup> metals has so far remained elusive. We report here on the preparation and full characterization of the first homoleptic phosphinine–iridium­(III) complex, obtained by C–H activation of 2,4,6-triphenylphosphinine with [Ir­(acac)<sub>3</sub>]. This result opens up new perspectives for the implementation of such aromatic heterocycles in more applied research fields.
