摘要：

The electroreduction of Zn(IT) ions in 1 M NaClO4 in the presence of thiolactams has been studied by means of the faradaic impedance method in wide frequency ranges. The standard rate constants are found to be a linear function of the surface excesses of thiolactarns. Catalytic activity of thiolactams increases in the following order: thiopyrrolidone, thiopiperidinone, thiocaprolactam; the enthalpies of activation decrease in this order. The differences in the catalytic activity of thiolactams result mainly from the double layer effect.
