Synthesis and Insecticidal Activity of N1-Pyridylmethyl-N-Arylacyl-Urea Derivatives
Abstract:
Ten N1-pyridylmethyl-N-arylacyl-urea derivatives were synthesized by the nucleophilic addition reaction of N-alkyl-(2-chloro-5-pyridylmethyl)amine with 2,6-difluorophenylacyl isocyanate, and characterized by IR, 1H NMR and elemental analysis. Preliminary biological tests showed that these compounds have good insecticidal activity against Nephotettix cincticeps and Mosquito larvae, especially, compounds 3f and 3j which could give 100% mortality for Nephotettix cincticeps in dosage with mass fraction of 5×10-5%.
