DIOXOLANYL- AND DIOXANYL-SUBSTITUTED DIAZOLES AND TRIAZOLES; DIOXOLANE AND DIOXANE INTERMEDIATES; AND PLANT ANTIFUNGAL COMPOSITIONS

摘要

Disclosed are compounds, having the general formula: (I) wherein: m=0, 1, 2; n=0, 1 with the condition that when m=0, also n=0; p=0, 1; q=1, 2; X is either oxygen or sulphur; A=N, CH; R is H, CH3, F; R1 is selected from chlorine, bromine, fluorine, CF3, phe=nyl, C1-C2-alkoxy, C1-C2-haloalkoxy, alkylthio, haloalkyl=thio, wherein the halogen is Cl, Br, F; R2 is selected from H, chlorine, bromine, fluorine; Rf is selected from the group formed by alkyls containing from 2 to 4 carbon atoms, and containing at least 4 atoms of halogen selected from F, Cl and Br, of which at least 3 are F atoms; alkenyls and alkynyls containing up to 4 carbon atoms, containing at least 2 F atoms and, optionally, other halogens selected between Cl and Br. The present invention relates to azolyl-derivatives, more particularly to substituted azolyldioxanes and azolyldioxolanes, endowed with high fungicidal activity, to the process for their preparation, and to their related use in the agrarian field.
