Mechanistic studies of the oxidative cleavage of the molybdenum-mercury bonds in [CpMo(CO)2(PPh3)]2Hg

Chemical or electrochemical oxidation of the trimetallic complex [CpMo(CO)2(PPh3)]2Hg (Cp = η5-C5H5) occurs in two one-electron steps. The first electron transfer generates a transient cation which undergoes Mo-Hg bond cleavage to generate a 16-electron species, [CpMo(CO)2(PPh3)]+, and a mercury-centered radical, CpMo(CO)2(PPh3)Hg?. To account for the products, it is proposed that the radical dimerizes and then reacts with half of the available 16-electron cation to form an observable pentametallic intermediate. The second electron transfer generates [CpMo(CO)2(PPh3)Hg]+ and returns the 0.5 mol of [CpMo(CO)2(PPh3)]+ which was incorporated into the intermediate. The mercury-containing cation subsequently eliminates metallic mercury to yield a second mole of [CpMo(CO)2(PPh3)]+. The 16-electron cation coordinates solvent or other available neutral or anionic ligands to yield 18-electron complexes.
