Contrasting ligand photolabilisations in the acetyl complexes [(η5-C5R5)Fe(CO)(PPh3)COMe](R = H, Me)
Abstract
While the primary photochemical process for [(η5-C5H5)Fe(CO)(PPh3)COMe] is exclusive loss of carbon monoxide to generate [(η5-C5H5)Fe(CO)(PPh3)Me], that for [(η5-C5Me5)Fe(CO)(PPh3)COMe] is exclusive loss of triphenylphosphine to generate [(η5-C5Me5)Fe(CO)2Me].
