The present invention relates to a compound of formula (I) wherein: R1 is C1-C3alkoxy, C1-C2alkoxy-C1-C3alkoxy, C1-C2fluoroalkoxy, ethyl, n-propyl, n-butyl, cyclopropyl or ethynyl; R2 is hydrogen, ethyl, n-propyl, cyclopropyl, vinyl, ethynyl, C1-C3alkoxy, C1-C3fluoroalkyl, C1-C2fluoroalkoxy, C1-C2alkoxy-C1-C3alkoxy-, or C1fluoroalkoxy-C1-C3alkoxy-; provided that when R1 is ethyl, n-propyl, n-butyl, cyclopropyl or ethynyl, then R2 is hydrogen, ethyl, n-propyl, cyclopropyl, vinyl or ethynyl; and Y is O, S, S(O), S(O)2, N(C1-C2alkyl), N(C1-C2alkoxy), C(O), CR8R9 or —CR10R11CR12R13—; and G, R3, R4, R5 and R6 are as defined herein; wherein the compound of formula (I) is optionally present as an agrochemically acceptable salt thereof. These compounds are suitable for use as herbicides. The invention therefore also relates to a method of controlling weeds, especially grassy monocotyledonous weeds, in crops of useful plants, comprising applying a compound of formula (I), or a herbicidal composition comprising such a compound, to the plants or to the locus thereof.
本发明涉及式 (I) 的化合物,其中:R1是C1-C3烷氧基、C1-C2烷氧基-C1-C3烷氧基、C1-C2氟烷氧基、乙基、正丙基、正丁基、环丙基或乙炔基;R2是氢、乙基、正丙基、环丙基、乙烯基、乙炔基、C1-C3烷氧基、C1-C3氟烷基、C1-C2氟烷氧基、C1-C2烷氧基-C1-C3烷氧基或C1-氟烷氧基-C1-C3烷氧基;条件是当 R1 是乙基、正丙基、正丁基、环丙基或乙炔基时,则 R2 是氢、乙基、正丙基、环丙基、乙烯基或乙炔基;且 Y 是 O、S、S(O)、S(O)2、N(C1-C2 烷基)、N(C1-C2 烷氧基)、C(O)、CR8R9 或 -CR10R11CR12R13-;G、R3、R4、R5 和 R6 如本文所定义;其中,式(I)化合物任选以其农用化学品可接受盐的形式存在。这些化合物适合用作除草剂。因此,本发明还涉及一种控制有用植物作物中杂草,特别是禾本科单子叶杂草的方法,包括将式(I)化合物或包含这种化合物的除草组合物施用到植物或其所在地。
