呋喃酚经醚化、傅克酰化、α-溴代、噻唑环化和亚胺化等反应合成了16种4-(7-甲氧基-2,2-二甲基-2,3-二氢苯并呋喃-5-基)-2-苄亚氨基噻唑新化合物.化合物的结构经1H NMR、质谱和元素分析等确证.杀虫活性实验结果表明,化合物2a和2i在500 mg/L对棉红蜘蛛死亡率分别为53.10%和67.71%,杀菌活性实验结果表明,化合物2a和2k在25 mg/L对油菜菌核病菌抑制率分别为57.9%和59.8%,除草活性实验结果表明,2l在2250 g.ai/ha浓度下对苘麻、刺苋、藜具有一定的除草活性.
Carbofuran was synthesized by the reaction of etherification, Friedenylation, α-bromo, thiazole cyclisation and imidization. The results showed that 16 kinds of 4- (7-methoxy-2,2-dimethyl- Hydrobenzofuran-5-yl) -2-benzyliminothiazole. The structures of the compounds were confirmed by 1H NMR, MS and elemental analysis. The insecticidal activities of compounds 2a and 2i showed that the compounds 2a and 2i exhibited the highest activity at 500 mg / The mortality of spider mites was 53.10% and 67.71%, respectively. The results of bactericidal activity showed that the inhibitory rates of compounds 2a and 2k at 25 mg / L on B. sclerotiorum were 57.9% and 59.8%, respectively. The herbicidal activity showed that 21% In the 2250 g.ai/ha concentration of sesame, amaranth, quinoa has some herbicidal activity.
