“…(3)], which is unstable and consumed by radical coupling on the CV (ms) timescale. [20] The weak Nernstian couple at À1.4 V observed for 1 and 2, but not for 3, is attributed to the reduction of the Hantzsch dihydropyridine dimer formed by coupling of the radical from the previous HE + -centered reduction.

“…Understanding its multifaceted mechanism is a challenging task. [7][8][9][10][11][12] We recall that the reduction of Nmethylpyridinium yields the prototypical methyl viologen (MV). [1][2][3][4] Organic compounds containing the bio-relevant pyridinium motif are suitable models for examination of such electrochemical structure-reactivity relationships.…”

“…The electrochemical reduction of pyridinium cations has been extensively investigated [1][2][3][4][5][6][7][8][9][10][11], in particular as a model for the reduction of NAD + , a natural coenzyme [11,12] and of MTPP + , a biological metabolite of MPTP, a neurotoxin involved in ParkinsonÕs disease [5,[13][14][15]. Numerous results indicate that their reduction generally occurs via two distinct one-electron steps.…”
