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

Abstract

Access to homoleptic phosphinine-based coordination compounds of d6 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)3]. This result opens up new perspectives for the implementation of such aromatic heterocycles in more applied research fields.
