New 3-substituted 1-azolyl-3-methyl-1-phenoxy-butan-2-ones and -ols of the general formula ##STR1## in which Az represents 1,2,4-triazol-1-yl, 1,2,4-triazol-4-yl or imidazol-1-yl, B represents the keto group or the CH(OH) group, Y represents oxygen or sulphur, R represents halogenoalkyl, optionally substituted phenyl or optionally substituted benzyl, or provided Y represents sulphur, may represent alkyl and X.sup.1, X.sup.2 and X.sup.3 are selected independently and each represent hydrogen, halogen, alkyl, halogenoalkyl, alkoxy, alkylthio, alkylsulphonyl, nitro, cyano, alkoxycarbonyl or optionally substituted phenyl, are obtained if halogenoether ketones are reacted with 1,2,4-triazole or imidazole in the presence of a diluent and of an acid-binding agent, and, if appropriate, the keto derivatives thus obtained are reduced. The compounds, as such or as their acid-addition salts or metal-salt complexes, have fungicidal activity, for example against those fungi which cause powdery mildew diseases or cause rice diseases.
通用公式为##STR1##的新3-取代1-唑基-3-甲基-1-苯氧基-丁酮和-醇,其中Az代表1,2,4-三唑-1-基,1,2,4-三唑-4-基或咪唑-1-基,B代表酮基或CH(OH)基团,Y代表氧或硫,R代表卤代烷基,可选择取代苯基或可选择取代苄基,或者当Y代表硫时,可能代表烷基,X.sup.1、X.sup.2和X.sup.3分别独立选择且代表氢、卤素、烷基、卤代烷基、烷氧基、烷基硫基、烷基磺酰基、硝基、氰基、烷氧羰基或可选择取代苯基,如果卤代醚酮在稀释剂和酸中和剂的存在下与1,2,4-三唑或咪唑反应,就会获得这些化合物,如此获得的酮衍生物可以被还原。这些化合物本身或其酸盐或金属盐络合物具有杀真菌活性,例如对引起白粉病或稻病的真菌具有活性。
