Observation of Inter-Metal Carbonyl Exchange in [(η5-C5H5)2Mo2(CO)6] and [(η5-C5H5)2MoW(CO)6

Abstract

Inter-metal carbonyl exchange in [(η5-C5H5)2Mo2(CO)6] and [(η5-C5H5)2MoW(CO)6], via [(η5-C5H5)2Mo2(μ-CO)2(CO)4] and [(η5-C5H5)2MoW(μ-CO)2(CO)4], has been observed by 13C NMR spectroscopy. The ΔG⧧ for the exchange is 13.9 ± 0.2 kcal mol-1 for the gauche isomer of [(η5-C5H5)2Mo2(CO)6] and 14.9 ± 0.2 kcal mol-1 for the trans isomer.
