SUBSTITUTED 2, 4-DIAMINO-5-CYANOPYRIMIDINE AND INSECT AND MITE CONTROL METHOD USING THE SAME

The invention relates to novel substituted 2,4-diamino-5-cyano-pyrimidines of formula (I) wherein R1 is hydrogen, C1-C6alkyl, C2-C6alkenyl or C2-C6alkynyl, R2 is hydrogen, C1-C10alkyl or C3-C6cycloalkyl, or R1 and R2, when taken together, are a radical selected from the group consisting of-(CH2)3-,-(CH2)4 and-(CH2)5, R5 is hydrogen or a radical-CO-R5 or-SO2-R6, R4 is a radical selected from the group consisting of -NH2,-NH-CO-R5,-NH-SO2-R6, or -NH-CH=N-R10; R5 is hydrogen, C1-C12alkyl, C3-C6cycloalkyl, C1-C6alkoxy, perhalogenated C1-C3alkyl or the radical R6 is C1-C6alkyl, R7 is hydrogen or C1-C6alkyl, R8 and R9 are each independently of the other hydrogen or C1-C6alkyl or, when taken together, are a radical selected from the group consisting of-(CH2)3-,-(CH2)4-and-(CH2)5, R10 is a radical-SO2-R13 or R11 and R12 are each independently of the other hydrogen or C1-C6-alkyl or, when taken together, are a radical selected from the group consisting of-(CH2)3-,-(CH2)4-and-(CH2)5, R13 is C1-C10alkyl, C1-C10alkyl which is substituted by up to 10 halogen atoms, or is C3-C6cycloalkyl R14 and R15 are each independently of the other C1-C10alkyl; and X and Y are each independently of the other oxygen or sulfur, and salts thereof, to the preparation and intermediates for the preparation thereof, and to compositions containing these compounds for controlling insects and representatives of the order Acarina, in particular plant-destructive feeding insects and ectoparasites that attack animals.
