Abstract

Abstract: Condensation of 3-(3′-pyridyl)-4-amino-5-mercapto-1,2, 4-triazole 4 with aromatic or fatty acids in the presence of phosphorus oxychloride gave 24 novel 3-(3′-Pyridyl)-6-alkyl/aryl-s-triazolo[3,4-b]-1, 3,4-thiadiazoles 5_a-x. Their structures were confirmed by elemental and spectral analyses. Some of the compounds were found to have some moderately fungicidal and herbicidal activities.

Key words: s-triazolo-thiadiazole, herbicide, synthesis, fungicidal activity
