A series of benzotriazole-azo-phenol/aniline derivatives were prepared and evaluated for their antifungal activities against six phytopathogenic fungi such as Fusarium graminearum, Fusarium solani, Alternaria alternate, Valsa mali, Botrytis cinerea, and Curvularia lunata. Among them, compounds IIf, IIn, and IIr showed a broad-spectrum of potent antifungal activities. Especially some compounds displayed 3.5–10.8 folds more potent activities than carbendazim against A. alternata and C. lunata. Notably, compounds IIc, IIm, and IIr exhibited good protective and therapeutic effects against B. cinerea at 200 μg/mL. Their structure-activity relationships were also discussed.

一系列苯并三唑偶氮-苯酚/苯胺衍生物的制备并评价它们对六种植物病原性真菌如抗真菌活性禾谷镰孢，腐皮镰孢，链格孢互生，苹果树腐烂病菌，灰霉病和新月弯孢霉。其中，化合物IIf，IIn和IIr表现出广谱的有效抗真菌活性。特别是一些化合物显示出比针对多菌灵3.5-10.8倍更有效的活动链格孢和C.孢。值得注意的是，化合物IIc，IIm和IIR表现出对良好的保护效果和治疗效果灰霉病在200微克/毫升。还讨论了它们的构效关系。
