通式[I]所代表的异�唑啉衍生物如式Ⅰ其中R1和R2可相同或不同，并分别是烷基；R3、R4、R5和R6分别是氢原子；Y代表任选被取代的含有选自氮原子、氧原子和硫原子的5-6元芳族杂环基或稠合芳族杂环基；且n是0-2的整数。所述异�唑啉衍生物具有优良的除草作用和在农作物与杂草之间的优良选择性。 An isoxazoline derivative which is represented by the general formula: [I] wherein R 1 and R 2 represent an alkyl group and may be the same or different, R 3 , R 4 , R 5 and R 6 represent a hydrogen atom, Y is a thiophen-3-yl group and the thiophehe ring is substituted with the substituent group ± at the 2- and 4-positions; or a isoxazol-4-yl group and the isoxazole ring is substituted with the substituent group ± at the 3- and 5-positions; or a isothiazol-4-yl group and the isothiazole ring is substituted with the substituent group ± at the 3- and 5-positions; or a pyridine-3-yl group and the pyridine ring is substituted with the substituent group ± at the 2- and 4-positions; or a pyrimidin-5-yl group and the pyrimidine ring is substituted with the substituent group ± at the 4- and 6-positions, and n represents an integer of 0 to 2. The isoxazoline derivative exhibits excellent herbicidal effect and selectivity between a crop and a weed.
