摘要：
The effect of several proton-donating substituents upon the polarographic behavior of 2,1,3-thiadiazole has been studied. It is shown that, as a result of self-protonation, separate reduction of monoprotonated and unprotonated molecules of the depolarizer takes place in aqueous neutral, nonbuffered media. It has been found that the chief factor determining the half-wave potential shift towards more positive values in dimethylformamide solutions is the proton-donating effect of the carboxy or hydroxy groups in the depolarizer.
