A series of salicylic acid-oriented thiourea derivatives was conveniently synthesized via multi-steps mainly including
alkylation, chlorination, nucleophilic substitution and addition reaction. The structure of all these newly synthesized
derivatives was confirmed and characterized by IR, 1H NMR and MS. The preliminary bioassay indicated that these
new compounds have some herbicidal activity or plant growth regulating activity against tested plants.
Keywords: Thiourea, Salicylic acid, Synthesis, Herbicidal activity, Plant growth regulating activity.
