Abstract

Abstract: Fifteen new compounds with the general formula:(这里有图片19930420-512-1.gif)in which ARis CH₃, C₂H₅, C₃H₇, C₄H₉, C₅H₁₁, 4-XC₅H₄(X-H, F, Cl, Br, I, CH₃, CH₃O, NO₂), 2-ClC₆H₄ 3-ClC₆H₄ have been prepared through the cyclization of 3-(α-naphthylmethylene)-4-amino-5-mercapto-1,2, 4-triazoie(3) with aliphatic earboxyhc acids and aromatic carboxylic acids in the presence of phosphorus oxychloride.The structures of the products were proved by ¹H NMR, 1R, MSand elemental analysis, it was found that some of these compounds have herbicidai and fungical activities.

Key words: Synthesis, 3-(α-Naphthyimethylene)-6-atkyl aryi-S-triazoio[3,4-b]-1,3,4-thiadiazols, Biological activities
