Abstract:
A pyrimidine compound of formula I in whichR1 represents C1-C10-alkyl, C1-C10-haloalkyl, C2-C6-alkenyl, C2-C6-alkynyl, C4-C8-alkadienyl, C1-C10-alkoxy, C3-C8-cycloalkly, phenyl, tri-C1--C6-alkyl-silyl, formyl or C1-C10-alkoxy-carbonyl, wherein R1 groups are unsubstituted or substituted by one to three groups Ra; Ra is halogen, nitro, cyano, hydroxy, or is C1-C10-alkyl, C3-C6-cycloalkyl, C3-C6-cycloalkenyl, C1-C10-haloalkyl, C3-C6-halocycloalkyl, C1-C10-alkoxy, C1-C10-haloalkoxy, C1-C10-alkoxycarbonyl, tri-C1--C4-alkyl-silyl, phenyl, halo- or dihalophenyl; R2 represents phenyl or C3-C6-cycloalkyl, which are unsubstituted or substituted by one to three groups Ra; R3 represents hydrogen, halogen, or is C1-C10-alkyl, C1-C10-alkoxy, C1-C10-alkylthio, C1-C10-alkylamino or di-C1-C10-alkylamino, which are unsubstituted or substituted by one to three groups Ra; R4 represents C1-C10-alkyl, C2-C6-alkenyl or C2-C6-alkynyl, which are unsubstituted or substituted by one to three groups Ra; and X represents O, S, NR5 or a single bond, wherein R5 represents hydrogen, C1-C10-alkyl or C1-C10-haloalkyl; or R1 and R5 together with the interjacent nitrogen atom form a heterocyclic ring selected from the group consisting of pyrrolidine, piperidine, tetrahydropyridine and azepane, which ring is optionally substituted by one or more C1-C10-alkyl groups.
