Abstract
Electrochemical studies show that [Ru(CO)2L(η4-cot)](1, L = CO or PPh3, cot = cyclo-octatetraene) undergoes a diffusion-controlled, but irreversible, one-electron oxidation at a platinum-bead electrode in CH2Cl2. The reaction of [Fe(η-C5H5)2][PF6] with (1, L = PPh3) in CH2Cl2 gives [Ru2(CO)4(PPh3)2(η2,η3: η′2,η′3-C16H16)][PF4]2via the C–C bond coupling of the radical cation [Ru(CO)2(PPh3)(C8H8)]+.Keywords
