Tuning Iridium(I) PCcarbenePFrameworks for Facile Cooperative N2O Reduction

A semiquantitative kinetic study correlates the rate of oxygen atom transfer from N₂O to an iridium carbon double bond with the donor properties of six PC_carbeneP pincer ligand frameworks. Two new rigid, electron rich ligands are described and shown to be the most effective for rapid, selective reaction with N₂O.<br
