文摘

Two series of benzoylphenylurea derivatives were synthesized as candidate propesticides by anucleophilic addition reaction between 2,6-difluronbenzoyl isocyanate and N-substitutedaniline. Thenew compounds were identified by ¹H NMR spectroscopy, electron ionization-mass spectrometry,and elemental analyses. The bioactivities of the new compounds were evaluated. All of thepropesticides reported here were soluble in most organic solvents, and their hydrophobicities wereimproved obviously. The result of the bioactivities of the new compounds against Oriental armywormshowed that some of the new compounds are good as compared to diflubenzuron and penfluron.Keywords: Propesticide; benzoylphenylurea; larvicidal activity; hydrophobicity; solubility; parentcompounds
