| abstract |
The invention relates to fungicidal compositions, characterized in that they contain a compound of the general formula I, <IMAGE> wherein R ° = subst. Phenyl or other (substituted) aromatic and heteroaromatic radicals, <IMAGE> R¹ = H, Cl, Br, (subst.) Alkyl; R² = H, Cl, Br, alkyl, (subst.) Phenyl, thienyl or furanyl, R³ and R <4> = H, (subst.) Alkyl, 2,2,6,6, -Tetramethylpiperidin-4-yl, Alkenyl, alkynyl or cycloalkyl, or R³ and R <4> together with the nitrogen atom to which they are attached, a (substituted) (bridged by a (C1-C2) alkylene chain) 3- to 9-membered saturated heterocycle ring, the as a ring member can also contain an O or S atom or the group NR <7>, -CH = CH-, C = O or -CH = N, or (subst.) 1,2,3,4-tetrahydroisoquinoline, or (subst.) 8-aza-1,4-dioxa-spiro- (4,5) decane. Numerous compounds from this group are new and are also covered by the invention. The compounds of formula I have a broad fungicidal activity against phytopathogenic fungi. |
