A series of novel N-cyano sulfonyimide derivatives containing trifluoromethyl pyridinamide were designed and synthesized by combination method of active substructure, and their structures were identified by 1H NMR, 13C NMR, 19F NMR and HRMS. Their antibacterial activity against Xanthomonas axonopodis pv. citri (Xac), Ralstonia solanacearum (R solanacearum), Xanthomonas oryzae pv. oryzae (Xoo) and insecticidal activity on Plutella xylostella (P. xylostella) were investigated. Some of the compounds were tested to display good antibacterial and moderate insecticidal activities. Among them, 3-chloro-N-(2-(N-cyano-S-(3,4-difluorobenzyl)sulfonimidoyl)ethyl)-5-(trifluoromethyl)picolinamide (G10) showed 67%, 53% and 48% activities against Xac, R. Solanacearum and Xoo at 200 mg/L, respectively. The antibacterial activity of 3-chloro-N- (2-(N-cyano-S-(2,5-difluorobenzyl)sulfonimidoyl)ethyl)-5-(trifluoromethyl)picolinamide (G17) against Xac was 69% and the inhibition rate of N-(2-(S-(2-bromo-4-fluorobenzyl)-N-cyanosulfonimidoyl)ethyl)-3-chloro-5-(trifluoromethyl)picolinamide (G14) on Xoo was 49%. N-(2-(S-(4-Bromo-2-fluorobenzyl)-N-cyanosulfonimidoyl)ethyl)-3-chloro-5-(trifluoromethyl)picolinamide (G1), 3-chloro-N-(2-(N-cyano-S-(3-fluorobenzyl)sulfonimidoyl)ethyl)-5-(trifluoromethyl)picolinamide (G7), 3-chloro- N-(2-(N-cyano-S-(2,4-difluorobenzyl)sulfonimidoyl)ethyl)-5-(trifluoromethyl)picolinamide (G8) and G10 also had moderate bactericidal activity at 100 mg/L, which are slightly higher than or comparable to that of the positive controls at the corresponding concentration. Moreover, compounds G10 and 3-chloro-N-(2-(N-cyano-S-(4-isopropylbenzyl)sulfonimidoyl)ethyl)-5-(trifluoromethyl)picolinamide (G11) also showed moderate insecticidal activity against P. xvlostella of 77% and 70% at 500 mg/L.
