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)₃]

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

Dibenzophosphapentaphenes: Exploiting P Chemistry for Gap Fine-Tuning and Coordination-Driven Assembly of Planar Polycyclic Aromatic Hydrocarbons

A synthetic route to planar P-modified polycylic aromatic hydrocarbons (PAHs) is described. The presence of a reactive σ³,λ³-P moiety within the sp²-carbon scaffold allows the preparation of a new family of PAHs displaying tunable optical and redox properties. Their frontier molecular orbitals (MOs) are derived from the corresponding phosphole MOs and show extended conjugation with the entire π framework. The coordination ability of the P center allows the coordination-driven assembly of two molecular PAHs onto a Au^I ion
