The electron transfer associated with proton transfer or bond breaking is an important process often presented in natural and biological systems. Understanding the mechanistic issues involved in the operation of these systems allows one to exploit and imitate them. Two bio-inspired systems have been studied by direct electrochemistry, the oxidation of a guanine paired to a cytosine with hydrogen bonds and the reduction of a cycloperoxide assisted by the presence of a proton donor group. The match between DNA bases through hydrogen bonding has no effect on the kinetic and thermodynamic of the oxidation of a guanine. The reaction is kinetically controlled by the first stage of electronic transfer and the mechanism involved is sequential. The ...
