Abstract
1-(2-chloropyridin-3-yl)-5-methyl-1H-1,2,3-triazole-4-carbonyl chloride(5) was synthe-sized using 2-chloropyridine as raw materials by diazotization,azide substitution,cyclization,and acyl chlorination.Then 13 novel title compounds were synthesized by acylation of(5) with substituted anilines.The structures of the compounds were confirmed by LC-MS and 1H NMR.The bioassay showed that all the compounds exhibit some insecticidal activity at concentration of 500 mg/L,among them,the mortality ratio of some compounds against Mythimna separate were 100%.While among the compounds,except the mortality ratio of ZJ-7 compounds against Mythimna separate were 100% at concentration of 100 mg/L,the mortality ratio of of the most compounds decreased significantly at concentration of 100 mg/L,some compounds even have no insecticidal activity.
