To improve their bioactivities of oxadiazole and triazole analogues, a series of N-2-perfluoroalkylethyl-substituted 1,3,4-oxadiazole-2-thiones 6a～6l and 1,2,4-triazole-5-thiones 9a～9l were synthesized and their structures were confirmed by 1H NMR, 19F NMR, IR, MS spectra and elemental analysis. The experimental results and the calculation showed that the hydrogen of NH group in heterocycle was more active than the hydrogen on CONH to finish alkyl-substitution reaction on nitrogen through the computing module Dmol3 of Materials Studio 3.0.
