Iron versus ruthenium oxidation in 1,1′-bis(diphenylphosphino)ferrocene-ruthenium(II) complexes:: EPR and spectroelectrochemical evidence

Oxidation of [Cp*RuH(dppf)] (1), dppf = 1,1'-bis(diphenylphosphino)ferrocene, and [(Cym)RuCl(dppf)](PF6) (2), Cym = p-cymene, occurs at ruthenium for 1 but yields a ferrocenium species for compound 2. (C) 2000 Elsevier Science S.A. All rights reserved.
