This process involves a neutral molecule and its radical anion and is accompanied with a significant activation barrier. Our observation that the electron stoichiometry for pyrimidine monomer reduction remains unchanged even at very low scan rates and the excellent reproducibility of the reduction wave during the cycling experiments indicate that a cyclodimerization process as described for vinylarylsulfones and vinyl pyridines did not occur in our case. In contrast, dimerization of the pyrimidine monomer radical anions at the C(6) position only involves minor electronic reorganization and is likely endowed with only a negligible if any activation barrier, thus making this step nearly diffusion controlled.

    • -1 respectively, leading to'the sole variation of the standard potential for adjustment with the experimental voltammetric curves. The uncertainty on the E°'s obtained is estimated to equal 25 mV.
