Substituents effects (H, NO2, CN, COOCH3, CH3, CH3O, (CH3)2N, Cl, F) on polarographic characteristics of the title quaternary salts have been studied in water, anhydrous acetonitrile, and aqueous ethanol. In the last solvent a gradual disappearance of one of the polarographic waves takes place. Probable course of the investigated electrode processes and accompanying chemical transformations is discussed.
