FERNANDA, M.  and  CARVALHO, N.N.. A Search for the Influence of the Electronic Characteristics of the Camphor Derived Ligands and Complexes on their Redox Properties . Port. Electrochim. Acta [online]. 2004, vol.22, n.1, pp.3-10. ISSN 0872-1904.

The electrochemical data obtained by cyclic voltammetry on several camphor-type (A, B and C) ligands and derived complexes are revised. A direct positive correlation is established between the redox potentials (anodic or cathodic) of the camphor species and the σp-Hammett parameter of the R group on the camphor skeleton. A study of the effect of the ligand on the redox properties of some Pd, Pt or Cu camphor complexes shows that the ligands influence either the anodic or cathodic processes but the characteristics of the metal drive the potential values

Keywords : Camphor ligands; complexes; redox properties; electronic properties.
