Article abstract of DOI:10.1039/DT9800000634

Equilibrium and rate data have been measured for the ligand-substitution rection 4-C6H5CH=ChCh=NC6H5)-(CO)2L> + CO = 4-C6H5CH=CHCH=NC6H5)(CO)3> + L where L=PPh3, AsPh3, or SbPh3.The reaction proceeds via a dissociative equilibrium of the η⁴ complexes to ? unsaturated complexes.Variations of the equlibrium and rate constants appear to be mainly associated with the basicity of the ligands.
