Exploring pathways for activation of carbon monoxide by palladium iminophosphines

DFT calculations on palladium(II) methyl complexes incorporating P/N ligands demonstrate that CO activation in the presence of competing ligands, such as CH₃CN or C₂H₄, occurs through an associative mechanism involving CO/ligand exchange, followed by migratory insertion of CO into the PdMe bond. Recent investigations into the Pd^II coordination of CO and C₂H₄ and their subsequent insertion into the PdMe bonds of complexes of the type [PdMe(iminophosphine)(NCMe)]⁺ are reported. A competitive advantage: DFT calculations on methyl-substituted palladium(II) complexes incorporating P/N ligands demonstrate that CO activation in the presence of competing ligands, such as CH₃CN or C₂H ₄, occurs through an associative mechanism involving CO/ligand exchange, followed by migratory insertion of CO into the Pd Me bond.
