Abstract
Sixteen novel Schiff's bases have been synthesised in high yields from 4-amino-3-(3-hydroxybutyl)-1H-1, 2, 4-triazole-5-thione. All the newly synthesised compounds have been characterised by elemental analysis, IR, 1H NMR, 13C NMR and MS. Plant growth-regulating activity tests showed that most compounds have remarkable effects on the growth of wheat and radish at a mass concentration of 50μg mL−1.
