Tridentate κ3-P,P,C iridium complexes: influence of ligand saturation on intramolecular C–H bond activation

Abstract

Whereas κ³-P,C,P-based donor ligands are ubiquitous across synthetic chemistry, related unsymmetric systems having κ³-P,P,C-coordination are comparatively rare. In this contribution, we expose a new κ³-P,P,C ligand system, bearing a C3-anionic linker and its coordination chemistry with iridium. The title ligand has been coordinated in saturated and unsaturated forms. The degree of ligand saturation affected an onward (and unusual) oxidative rearrangement reaction.
