Abstract

• Halogen complexes of ruthenium cyclopentadienyl ?CpRu?PTA?2X?; ?CpRu?PTA??PPh3?X?; ?CpRu?PPh3?2Cl?, and ?CpRu?mPTA??PPh3?X?+ ?Cp = C5H5; PTA = 1,3,5-triaza-7-phosphaadamantane; mPTA+ = ?1-methyl-1,3,5-triaza-7- phosphaadamantane?+; X = Cl-, I-? were investigated by electrospray mass spectrometry ?ESI-MS?, in flow-cell cyclic voltammetry, by microelectrodes, and by combined online electrochemistry and electrospray mass spectrometry ?EC/ESI-MS? in dimethyl formamide solution. Coordination changes and the structures of the initial compounds and the products of the electrooxidation of the Ru?II? complexes were traced by in situ EC/MSn experiments which revealed their fragmentation pathways. ESI-MS collision-induced dissociation fragmentations of the initial reactants and the oxidation products were explained by soft acid-hard base considerations taking into account the different nature of Ru?II?--Ru?IV? centers. The electrochemical studies show that it is possible to tune the formal potentials for the oxidation of ?CpRuL2X? complexes by over 300 mV by proper selection of the ligands. The increase of the redox potential by the different ligands follows the order PTA ? PPh3 ? mPTA+. We demonstrate a similarity between the propensity of the ligand to fragment out in the gas phase and its relationship to the formal potential of the complex. (literal)
