A series of 4-methyl-N-(5-substituted-1, 3,4-thiadiazol-2-yl)-1,2,3-thiadiazole-5-carboxamide 6a~6j. The
chemical structures were confirmed by 1H NMR, FTIR, MS, and elemental analysis. All the compounds were investigated
for antifungal activity. The antifungal activity results indicated that compound 6a exhibited good activities against C. arachidicola.
It can be compared with the commercial drug. The compounds 6e, 6f, 6i, 6j exhibited moderate activity.

In order to investigate the biological activity of novel thiourea compounds, some novel 1,2,3-
thiadiazole derivatives containing 1,3,4-thiadiazole were synthesized under phase transfer catalyzed condition(
PEG-600)by multi-step reactions. The chemical structures of all compounds were established by 1H
NMR, FTIR, MS, and elemental analysis, and some of these compounds were investigated for fungicidal
activity and plant growth regulatory activity. The bioassay results indicated that some of these compound
exhibited moderate activities.

unsubstituted in the 5-position, and a strong base such as an organolithium compound, sodamide, sodium methylsulfinyl carbanion, or potassium t-butoxide results in cleavage of the thiadiazole ring system with evolution of nitrogen and formation of alkalimetal alkynethiolate. Subsequent addition of an alkyl or acyl halide to the reaction mixture produces 1-alkynyl thioethers. 4-(5-Phenyl-1,2,3-thiadiazolyl)lithium
