<p>Electrochemical reduction of 4-nitropyridine-<i>N</i>-oxide (1) is a promising method for synthesising nitrogen-containing compounds, particularly those with pharmaceutical and fine chemical applications. The process can be finely tuned to produce various products, depending on the electrochemical conditions and the specific reagents used. Consequently, in this study the electrochemical reduction of 4-nitropyridine-<i>N</i>-oxide (1) in a buffered acetonitrile solution using carbon electrodes in a simple undivided cell has been investigated and leaded to the formation of several interesting products. The findings indicated, the electroreduction of 4-nitropyridine-<i>N</i>-oxide forms an unstable intermediate that is converted to 4,4'-(1-oxido diazene-1,2-diyl)bis(pyridine <i>N</i>-oxide) (P1) via a paired electrosynthesis process. Also, α and J₀ were evaluated as essential kinetic parameters associated with the irreversible cathodic electron-transfer process of 4-nitropyridine N-oxide (1). Additionally, the reduction of 1 in the presence of aryl sulfinic acid derivatives results in the synthesis of novel sulfonamides, (4-methylphenyl) sulfonamido)pyridine <i>N</i>-oxide (P2) and 4-(phenyl sulfonamide)pyridine <i>N</i>-oxide (P3). The structure of synthesized compounds was confirmed using ¹HNMR, ¹³CNMR, MS, and infrared (IR) spectroscopy.</p> Graphical Abstract <p></p>
