Abstract

Abstract: A series of novel 3-aryl-6-(1,1'-biphenyl-4-yl)-7H-1,2,4-triazolo[3,4-b][1,3,4 ]thiadiazines was synthesized by means of the reactions between 3-aryl-4-amino-5-mercapto-1,2,4-triazoles and 2-bromo-4'-phenylacetophenone. The structures of all the title compounds have been confirmed by virtue of elemental analysis, IR, ¹H NMR, ¹³C NMR and mass spectra. The characteristics of ¹³C NMR peaks of the compounds were investigated. The plant growth regulating effects of those compounds were also determined.

Key words: 7H-1,2,4-Triazolo[3,4-b][1,3,4]thiadiazines, Synthesis, Biological activity
