Hu, Chongbo published the artcileSynthesis and insecticidal activities of N-(tert-butyl)-N’-(fluorobenzoyl)pyridinecarboxylic acid hydrazide derivatives, Recommanded Product: 2-Chloroisonicotinic acid, the publication is Youji Huaxue (2016), 36(5), 1051-1059, database is CAplus.
In order to find novel diacylhydrazine derivatives which possessed high activities against pests, 20 novel N-(tert-butyl)-N’-(fluorobenzoyl)pyridinecarboxylic acid hydrazide derivatives of formula I [Py = substituted pyridine; R = H, F] were synthesized by introducing fluoro-contained Ph and pyridine into the basic structure of diacylhydrazines. Their structures were confirmed by 1H NMR, 13C NMR, IR and HRMS. The bioassay results indicated that most of the compounds exhibited more than 80 % mortality against Mythimna separata at the concentration of 500 mg/L. Among these compounds, N-(tert-butyl)-N’-(2,6-difluorobenzoyl)-N-2-chloronicotinohydrazine and N-(tert-butyl)-N’-(2,6-difluorobenzoyl)-N-2,5-dichloronicotinohydrazine exhibited 100 % and 80 % mortality against Mythimna separata at 10 mg/L, resp. The LC50 of compound N-(tert-butyl)-N’-(2,6-difluorobenzoyl)-N-2-chloronicotinohydrazine against Mythimna separata was 8.77 mg/L, and it showed about 0.51 times of toxicity against Mythimna separata than tebufenozide and had 1.5 times of toxicity against Plutella xylostella than tebufenozide.
