There are described new pyrimidine derivatives of the general Formula I
in which n is 0, 1 or 2;
R, is a) the group -CXRs, where X is oxygen or sulphur and R5 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 R5 is the group -NHR6, where R6 is substituted amino, substituted carbamoyl, optionally substituted alkylsul- phonyul, acyl or arylsulphonyl, and when n is 0 or when X is sulphur, R5 can also be alkyl, haloalkyl, aryl, aralkyl, alkoxycarbonylalkyl or arylamino;
b) cyano or the group -CXYR7, where X and Y are the same or different and are oxygen, sulphur or optionally substituted imino and R7 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 R4 group is haloalkoxy, R, can be hydrogen;
R2 and R3 are the same or different and are alkyl, and
R4 is alkyl, alkoxy, halogen, haloalkyl, haloalkoxy, nitro or
cyano. The compounds have fungicidal activity.
