This invention relates to substituted and unsubstituted alpha-aryl-alpha-phenylethyl-1H-1,2,4-triazole-1-propanenitriles, their enantiomorphs, acid addition salts and metal salt complexes. These compounds, enantiomorphs, salts and complexes are highly active broad-spectrum systemic fungicides effective in controlling phytopathogenic fungi such as corn helminthosporium, barley helminthosporium, cucumber downy mildew, cucumber powdery mildew, cucumber anthracnose, botrytis, tomato early blight, tomato late blight, grape downy mildew, bean powdery mildew, peanut cercospora, rice blast, rice sheath blight, wheat leaf rust, wheat septoria nodorum, wheat powdery mildew and wheat stem rust. The invention also concerns a method of preparing alpha-aryl-alpha-triazolylmethylacetonitrile compounds by reacting an aryl-acetonitrile compound with a halomethyltriazole.
本发明涉及取代和未取代的α-芳基-α-苯基乙基-1H-1,2,4-三唑-1-丙腈,它们的对映异构体,酸加成盐和金属盐络合物。这些化合物、对映异构体、盐和络合物是高效的广谱系统杀菌剂,能有效控制植物病原真菌,如玉米赤霉病菌、大麦赤霉病菌、黄瓜霜霉病、黄瓜白粉病、黄瓜炭疽病、灰霉病、番茄早疫病、番茄晚疫病、葡萄霜霉病、豆粉病、花生青枯病、水稻稻瘟病、水稻纹枯病、小麦叶锈病、小麦节疣病、小麦白粉病和小麦锈病。本发明还涉及通过将芳基-丙腈化合物与卤代甲基三唑反应制备α-芳基-α-三唑基甲基乙腈化合物的方法。
