Effect of heteroatom and functionalitysubstitution on the oxidation potential of cyclicnitroxide radicals: role of electrostatics inelectrochemistry†

Zhang, Kai; Noble, Ben; Mater, Adam; Monteiro, Michael J; Coote, Michelle; Jia, Zhongfan


The oxidation potential of a test set of 21 nitroxide radicals, including a number of novel compounds, has been studied experimentally in acetonitrile and correlated with theoretical calculations. It was found that both Hammett constants (σp) of the substituents on the nitroxide radicals and hyperfine splitting constants of the respective nitrogen atoms (αN) were well correlated to their experimental oxidation potentials. Theoretical calculations, carried out at the...[Show more]
