There are described new pyrimidine derivatives of the general formula I ##STR1## in which n is 0, 1 or 2; R.sub.1 is (a) the group --CXR.sub.5, where X is oxygen or sulphur and R.sub.5 is hydrogen, a nitrogen or sulphur containing heterocyclic group, which can contain other hetero atoms, optionally substituted alkenyl, acyl, alkoxycarbonyl, alkyl substituted by aryloxy, or optionally substituted mono- or dialkylamino; or R.sub.5 is the group --NHR.sub.6, where R.sub.6 is substituted amino, substituted carbamoyl, optionally substituted alkylsulphonyl, acyl or arylsulphonyl, and when n is 0 or when X is sulphur, R.sub.5 can also be alkyl, haloalkyl, aryl, aralkyl, alkoxycarbonylalkyl or arylamino; (b) cyano or the group --CXYR.sub.7, where X and Y are the same or different and are oxygen, sulphur or optionally substituted imino and R.sub.7 is optionally substituted alkyl, aryl, acyl or a nitrogen or sulphur containing heterocyclic group, which can contain other hetero atoms; or (c) when n is 1 or 2 and at least one R.sub.4 group is haloalkoxy, R.sub.1 can be hydrogen; R.sub.2 and R.sub.3 are the same or different and are alkyl, and R.sub.4 is alkyl, alkoxy, halogen, haloalkyl, haloalkoxy, nitro or cyano. The compounds have fungicidal activity.
描述了一种新的嘧啶衍生物,其一般式为I ##STR1## 其中n为0、1或2;R.sub.1为(a)基团--CXR.sub.5,其中X为氧或硫,R.sub.5为氢、含氮或硫的杂环基团,可含有其他杂原子,可选地取代的烯基、酰基、烷氧羰基、芳基取代的烷基、或可选地取代的单烷基或二烷基氨基;或R.sub.5为基团--NHR.sub.6,其中R.sub.6为取代氨基、取代氨基甲酰基、可选地取代的烷基磺酰基、酰基或芳基磺酰基,当n为0或X为硫时,R.sub.5还可以是烷基、卤代烷基、芳基、芳基烷基、烷氧羰基烷基或芳基氨基;(b)氰基或基团--CXYR.sub.7,其中X和Y相同或不同,为氧、硫或可选地取代的亚胺基,R.sub.7为可选地取代的烷基、芳基、酰基或含氮或硫的杂环基团,可含有其他杂原子;或(c)当n为1或2且至少一个R.sub.4基团为卤代烷氧基时,R.sub.1可以为氢;R.sub.2和R.sub.3相同或不同,为烷基,R.sub.4为烷基、烷氧基、卤素、卤代烷基、卤代烷氧基、硝基或氰基。这些化合物具有杀真菌活性。
