Ten novel polyhalo benzoylphenylurea chitin inhibitor derivatives have been synthesized in over 30%~50% yields from readily available starting material chlorothalonil 1 via fluorine exchange, aminolysis, decarboxylation and acylation reactions. All products were characterized by 1H NMR, HREIMS and IR spectra. Preliminary bioactive research showed that some of the synthesized compounds have the potential insecticidal activities against Mythimna separata and Culex pipiens pallens.

Key words: chitin inhibitor, insecticidal activity, benzoylphenylurea, chlorothalonil
