Abstract:Fungicide boscalid was prepared by the reaction of 2-chloronicotinoyl chloride with the intermediate biphenyl-2-amine prepared from the starting materials 2-iodinphenylamine and 4-chlorophenyl boric acid via Suzuki reaction,with the yield 71.2%. The structure was confirmed by 1H NMR. The bioasay results of bioactivity test showed that boscalid had a broad-spectrum and good fungicidal activity,and gave respective 85% and 70% control against powdery mildew and grey mold at 25 mg/L. |
Key words:boscalid;synthesis;fungicidal activity |
