Tuning Iridium(I) PCcarbeneP Frameworks for Facile Cooperative N2O Reduction

A semiquantitative kinetic study correlates the rate of oxygen atom transfer from N<sub>2</sub>O to an iridium carbon double bond with the donor properties of six PC<sub>carbene</sub>P pincer ligand frameworks. Two new rigid, electron rich ligands are described and shown to be the most effective for rapid, selective reaction with N<sub>2</sub>O.<br>
