Abstract

Dissociation of ligands from Fe(CO)3L2 and Fe(CO)4L (L = PPh3, P(OPh)3, AsPh3) has been investigated by reaction with carbon monoxide. These complexes are relatively inert, requiring temperatures considerably in excess of 100 °C. The relative inertness of 18-electron complexes of iron is considered. The order of ligand lability from Fe(CO)3L2 is AsPh3 > PPh3 > P(OPh)3, which apparently represents the general bond strength to low-valent metal centers.
