The invention relates to 2-substituted pyrimidines of formula (I), in which the index n and the substituents R1, R2 and R3 are defined as cited in the description. R4 is defined as follows: R4 corresponds to one of the formulae (II), in which X represents a direct bond, -(C=0)-, -(C=0)-NH-, -(C=0)-0-, -0- , -NRc-, whereby the respective molecule on the left is bonded to the nitrogen atom; Ra represents hydrogen, methyl, benzyl, trifluoromethyl, allyl, propargyl or methoxymethyl; Rb represents hydrogen, C1-C6 alkyl, C2-C6 alkynyl; Rc represents hydrogen, methyl or C1-C4 acyl; and Z represents S or NRb. The aliphatic groups of the radical definitions of Ra, Rb and/or Rc can in turn carry one or two groups Rw, whereby Rw represents halogen, ORx, NHRx, C1-C6 alkyl, C1-C4 alkoxycarbonyl, C1-C4 acylamino, [1,3]dioxolane-C1-C4 alkyl, [1,3]dioxane-C1-C4 alkyl and Rx represents hydrogen, methyl, allyl or propargyl. The invention also relates to a method for producing said compounds, to agents containing said compounds and to the use of the latter as pesticides.

La présente invention concerne des pyrimidines 2-substituées de formule (I) dans laquelle l'indice n et les substituants R?1¿, R?2¿ et R?3¿ sont tels que définis dans le descriptif, et R?4¿ est représenté par une formule (II) dans laquelle: X est une liaison directe, -(C=0)-, -(C=0)-NH-, -(C=0)-0-, -0-, -NR?c¿-, la partie respective gauche de la molécule étant liée à l'atome d'azote; R?a¿ est hydrogène, méthyle, benzyle, trifluorméthyle, allyle, propargyle ou méthoxyméthyle; R?b¿ est hydrogène, alkyle en C¿1?-C¿6?, alcynyle en C¿2?-C¿6?; R?c¿ est hydrogène, méthyle ou acyle en C¿1?-C¿4?; Z est S ou NR?b¿; les groupes aliphatiques des radicaux R?a¿, R?b¿ et/ou R?c¿ portant un ou deux groupes R?w¿ qui représente(nt) halogène, OR?x¿, NHR?x¿, alkyle en C¿1?-C¿6?, alcoxycarbonyle en C¿1?-C¿4?, acylamino en C¿1?-C¿4?, [1,3]dioxolane-C¿1?-C¿4?-alkyle, [1,3]dioxane-C¿1?-C¿4?-alkyle, R?x¿ représentant hydrogène, méthyle, allyle ou propargyle. L'invention a également pour objet un procédé pour préparer ces composés, des substances contenant ces composés et leur utilisation en tant que pesticides.
