Abstract
A series of 5,6-diphenyl-3-substituted-thio-1,2,4-triazines (II-V) was prepared by treating 5,6-diphenyl-1,2,4-triazine-3-thiol (I) with corresponding electrophiles. Condensation of IV or V with 1,2-phenylenediamines gave 2-[(5,6-diphenyl-1,2,4-triazin-3-yl) thiomethyl-1H-benzimidazoles] (VI). IV was converted into its corresponding hydrazide (VII) by the action of hydrazine hydrate. N-Benzylidene derivatives (VIII) were prepared by the condensation of VII with appropriate aryl or heterocyclic aldehydes. The pesticidal activities of all the compounds thus synthesised were determined.
