Electrochemically-induced and electron transfer chain-catalysed substitution reactions in dinuclear molybdenum carbonyl complexes [(η5-C5H5)2Mo2(CO)4(η-SR)2] and [(η5-C5H5)2Mo2(CO)4(η-SR)2]2+[A]2(R = Me, Ph; A = BF4– or PF6–)
Abstract
A radical cation, transiently produced in a single step two-electron transfer, is shown to be the reactive species in a substitution process which can be oxidatively-induced or catalysed via an electron transfer chain mechanism.
