"Chemical compounds". The present invention relates to a fungicidal active compound of formula (I): wherein Het is a substituted 5- or 6-membered heterocyclic ring. R¬ 1¬ is hydrogen, formyl, CO-C 1-4-alkyl, COO-C 1-4-alkyl, C 1-4-(C 1-4) alkoxyalkylene, CO-C ~ 1-4-C 1-4 alkylenoxyalkyl, propargyl or alenyl; R¬2¬, R¬3¬, R¬4¬ and R¬5¬ are each independently hydrogen, halogen, methyl or CF ~ 3 ~; each of R¬ 6¬ is independently halogen, methyl or CF ~ 3 ~; R¬ 7¬ is (Z) ~ m ~ C <sym> C (Y¬ 1¬), (Z) ~ m ~ C (Y¬ 1¬) = (Y¬ 2¬) (Y¬ 3¬) or tri (C 1-4) alkylsilyl; X is O OR S; y¬ 1¬, y¬ 2¬ and y¬ 3¬ are each independently hydrogen, halogen, C ~ 1-6 ~ alkyl ¢ optionally substituted by one or more substituents each independently selected from halogen, hydroxy, C 1-4 alkoxy, C 14 halo alkoxy, C 1-4 alkylthio, C 1-4 haloalkyl, C 1-4 alkylamino, di (C 1-4 ~) alkylamino, C 1-4 alkoxycarbonyl, C 1-4 alkyl alkylcarbonyl and tri (C 1-4) alkylsilyl, C 2-4 alkenyl optionally substituted by one or more substituents each one independently selected from halogen !, C 2-4 ~ alkynyl ¢ optionally substituted by one or more substituents each independently selected from halogen !, C 3-7 ~ cycloalkyl ¢ substituted optionally by one or more substituents selected from halogen, C 1-4 alkyl and C 1-4 haloalkyl; or tri (C 1-4) alkylsilyl; C 1-4 alkylene is optionally substituted by one or more substituents each independently selected from hydroxy, cyano, C 1-4 alkoxy, halogen, C 1-4 haloalkyl, C 1-4 haloalkoxy, C 1-4 alkylthio, COOH and COOC 1-4 alkyl; m is 0 or 1; and n is 0, 1 or 2; The invention also relates to novel intermediates used for the preparation of such compounds, agrochemical compositions comprising at least one of the novel compounds as the active ingredient and the use of the active ingredients or compositions in agriculture or horticulture for the control or the prevention of plant infestation by phytopathogenic microorganisms, preferably fungi. |
