Several ω-(5-arylamino-1,3,4-thiadiazol-2-thiol)-ω-(1H-1,2,4-triazol-1- yl)acetophenones 4a-i have been synthesized. The representative compounds exhibit some antifungal and plant growth regulatory activities. The structures of these compounds have been confirmed by elemental analyses, 1H NMR, IR and MS spectra.
Alkali catalyzed thermal cyclization of 1-substituted and 1,6-disubstituted 2,5-dithiobiureas: Formation of 1,2,4-triazolidine-3,5-dithiones and/or 1,3,4-thiadiazoline-5-thiones

Alkali catalyzed thermal cyclization of 1-alkyl and 1,6-dialkyl-2,5-dithiobiureas (I, R=alkyl, R'=H and R=R'=alkyl) results in the formation of 4-alkyl-1,2,4-triazolidine-3,5-dithiones (V) (alkyl=Me or Et) and 2-alkylamino-Δ2-1,3,4-thiadiazoline-5-thiones (VI) (alkyl=n-Pr or n-Bu).Under the same conditions, 1-alkyl-6-aryl-2,5-dithiobiureas (I, R=alkyl, R'=aryl) give 2-arylamino-Δ2-1,3,4-thiadiazoline-5-thiones (IX) (alkyl=Me, Et, n-Pr or n-Bu) and 4-alkyl-1,2,4-triazolidine-3,5-dithiones (V) also when the alkyl groups are Me or Et.
