Compounds of the formula
wherein X represents a hydrogen atom, a cyano group, a substituted or non-substituted alkoxy- or cycloalkyloxy group, an optionally substituted alkylthio- or arylthio group. a substituted or non-substituted alkyl group or a group -NRR', in which R is a hydrogen atom or an alkyl group, R' is a substituted or non-substituted alkyl- or aryl group, a cycloalkyl- or an acyl group and R and R' together with the interjacent nitrogen atom may form a heterocyclic ring, Y and Z independently are halogen atoms, alkyl-, alkoxy-or nitro groups and m and n each are 0, 1 or 2, whereby the same or different groups Y may be present when m equals 2 and the same or different groups Z when n equals 2. The compounds are prepared by reacting a nicotinic anilide with a thionyl halide. The intermediate phenylimino-c-(halo)methyl-pyridine is subsequently reacted with QX. wherein Q is hydrogen or an alkali metal.
The compounds are useful as fungicides and plant , growth regulants.
式中的化合物
其中 X 代表氢原子、氰基、取代或非取代的烷氧基或环烷氧基、任选取代的烷硫基或芳硫基。取代或非取代的烷基或基团-NRR',其中 R 是氢原子或烷基,R'是取代或非取代的烷基或芳基、环烷基或酰基,R 和 R'与相邻的氮原子可形成杂环、Y 和 Z 分别为卤素原子、烷基、烷氧基或硝基,m 和 n 分别为 0、1 或 2,其中,当 m 等于 2 时,可存在相同或不同的基团 Y,当 n 等于 2 时,可存在相同或不同的基团 Z。这些化合物是通过烟酰基苯胺与亚硫酰卤反应制备的。中间产物苯基亚氨基-c-(卤代)甲基吡啶随后与 QX 反应,其中 Q 为氢或碱金属。
这些化合物可用作杀真菌剂和植物生长调节剂。
