Contrasting ligand photolabilisations in the acetyl complexes [(η5-C5R5)Fe(CO)(PPh3)COMe] (R = H, Me)
Davies SG., Watkins WC.
While the primary photochemical process for [(η5-C 5H5)Fe(CO)(PPh3)COMe] is exclusive loss of carbon monoxide to generate [(η5-C5H 5)Fe(CO)(PPh3)Me], that for [(η5-C 5Me5)Fe(CO)(PPh3)COMe] is exclusive loss of triphenylphosphine to generate [(η5-C5Me 5)Fe(CO)2Me].
