The present invention is directed to novel pyrazole derivatives and their use as pesticidal agents. The pyrazole derivatives have Formula I:
or a salt thereof, where
R1 represents R5O, R5SO2, R5SO or R5S in which R5 is as defined herein;
X is halo, cyano, C1-6 alkoxycarbonyl, C2-6 alkynyl, optionally substituted C6-14 aryl or an optionally substituted 5- to 7-membered heteroaromatic ring linked to thiazole via a carbon-carbon bond;
R2 is hydrogen, amino, chloro, bromo, iodo, cyano, C1-6 alkoxy, C1-6 alkyl or C6-10 aryl; and
R3-R7 each represent hydrogen, halogen, straight- or branched-chain C1-4 alkyl or C1-4 alkoxy, either of which is unsubstituted or substituted by one or more halogen atoms, straight- or branched-chain C1-4 alkylthio or C1-4 alkylsulphinyl, either of which is substituted by one or more halogen atoms, nitro, cyano, or straight- or branched-chain C1-4 alkylsulphonyl group which is unsubstituted or substituted by one or more halogen atoms.
本发明涉及新型吡唑衍生物及其作为杀虫剂的用途。吡唑衍生物具有以下化学式:或其盐,其中R1代表R5O,R5SO2,R5SO或R5S,其中R5如本文所定义;X为卤素,氰基,C1-6烷氧羰基,C2-6炔基,可选地取代的C6-14芳基或通过碳-碳键与噻唑连接的可选地取代的5-至7-成员杂芳环;R2为氢,氨基,氯,溴,碘,氰基,C1-6烷氧基,C1-6烷基或C6-10芳基;以及R3-R7分别代表氢,卤素,直链或支链的C1-4烷基或C1-4烷氧基,其中任一者未被取代或被一个或多个卤素原子取代,直链或支链的C1-4烷硫基或C1-4烷基磺氧基,其中任一者被一个或多个卤素原子取代,硝基,氰基,或直链或支链的C1-4烷基磺酰基,未被取代或被一个或多个卤素原子取代。
