2-(N-phenylamino)pyrimidines of the formula I,
where:
R1, R3 independently of one another are cyano, C1-C8-alkyl, C2-C6-alkenyl, C2-C6-alkynyl, where the radicals alkyl, alkenyl and alkynyl may be substituted by cyano, halogen, C1-C4-alkoxy or C1-C4-alkoxycarbonyl, or are C3-C8-cycloalkyl or a group C(═NORx)Ry
R2 is halogen, C1-C8-alkyl, C2-C6-alkenyl, C2-C6-alkynyl, where the radicals alkyl, alkenyl and alkynyl may be substituted by cyano, halogen, C1-C4-alkoxy or C1-C4-alkoxycarbonyl, or
R1 and R2 together with the two linking carbon atoms form a fused-on partially unsaturated 4- to 8-membered ring which may be up to trisubstituted by identical or different substituents selected from the group consisting of C1-C4-alkyl, halogen and C1-C4-alkoxy-carbonyl, which may contain a carbonyl group and/or, in addition to the multiple bond of the pyrimidine ring, a double bond and/or which may be interrupted by O, S or N—(C1-C4-alkyl);
the substituents R4 to R8, Rx, Ry, Ra and Rb are as defined in the description;
are used as fungicides.
公式I中的2-(N-苯基氨基)嘧啶,其中:R1,R3彼此独立,为氰基,C1-C8-烷基,C2-C6-烯基,C2-C6-炔基,其中烷基,烯基和炔基基团可以被氰基,卤素,C1-C4-烷氧基或C1-C4-烷氧羰基取代,或者为C3-C8-环烷基或C(═NORx)Ry基团;R2为卤素,C1-C8-烷基,C2-C6-烯基,C2-C6-炔基,其中烷基,烯基和炔基基团可以被氰基,卤素,C1-C4-烷氧基或C1-C4-烷氧羰基取代,或者R1和R2与两个连接碳原子一起形成螺联的部分不饱和的4-到8-成员环,该环可以被相同或不同的取代基取代,所述取代基选择自C1-C4-烷基,卤素和C1-C4-烷氧羰基组成,可以含有一个羰基基团,除了嘧啶环的多重键之外,还可以具有一个双键和/或可以被O,S或N-(C1-C4-烷基)中断;取代基R4到R8,Rx,Ry,Ra和Rb如描述中所定义;用作杀菌剂。
