complexes by palladium-catalyzed coupling between η5-(iodo)cyclopentadienyl and η5(trimethyltin)cyclopentadienyl metal complexes. In the presence of Pd the (η5-iodocyclopentadienyl)metallo methyl derivatives of general formula (η5-IC5H4)M(CO)nCH3 (M = Fe, n = 2; M = W, n = 3; M = Mo, n = 3) undergo methyl-iodine exchange, to give the corresponding (η5-CH3C5H4)M(CO)nI complexes.
