✦ Synopsis

Electrode reactions of 2,2,6,6-tetramethylpiperidinenitroxide (TMPNO) and di-tertbutytnitroxide (DTBNO) at platinum in acetonitrile solution were investigated by means of linear sweep voltammetry and controlled potential coulometry. In the case of TMPNO, the voltammetric results were satisfied with diagnostic criteria for reversible charge transfer, and those of esr and coulometry led to one electron transfer. In the case of DTBNO, the coulometric results in which apparent number of electron was l/3 times the real one led to a mechanism with interesting series of reactions. This was also confirmed by CW-.

The cathodic behavior ofacetonitrile at a platinum electrode is strongly dependent on the cation of the supporting electrolyte, and contamination by moisture. Mixtures of supporting electrolytes can give anomalous effects under certain conditions; the results are consistent with the formation of hyd
