    • The present invention relates to novel cyclohexane-1,3-dione derivatives of formula (I) useful as herbicides and plant-growth regulants, wherein, X is selected from the group consisting of hydrogen, C1-C6 alkyl, C2-C6 alkoxy, halogen, C1-C6 haloalkyl, nitro, cyano, C1-C6 alkylthio, C1-C6 alkylsulfinyl, C1-C6 alkylsulfonyl, sulfamoyl, N-(C1-C6 alkyl)sulfamoyl and N,N-di(C1-C6 alkyl)sulfamoyl group; (X)n represents number of X substituents which may be the same or different on benzene ring, where n is 1, 2 or 3. Also, cyclohexyl moiety, one of the substituents on benzofuran ring, is substituted at 4, 5, 6 or 7 position. The (X)n cannot be filled only with hydrogens and the (X)n can substitute position where cyclohexyl moiety is not substituted; R1 is selected from hydrogen and C1-C4 alkyl group; R2 is selected from C1-C6 alkyl, C2-C6 alkenyl and C2-C6 alkynyl group; R3 is selected from hydrogen, C1-C6 alkyl, C1-C6 haloalkyl, C2-C6 alkenyl, C2-C6 haloalkenyl, C2-C6 alkoxyalkyl, C2-C6 alkylthioalkyl, benzyl and C2-C6 haloalkanoyl group; R4 is selected from hydrogen, alkali metal cation, alkaline earth metal cation, C1-C4 alkanoyl, C1-C4 haloalkanoyl and benzoyl group.
    • 本发明涉及可用作除草剂和植物生长调节剂的式(I)的新型环己烷-1,3-二酮衍生物,其中X选自氢,C 1 -C 6烷基,C 2 -C 6烷氧基, 卤素,C 1 -C 6卤代烷基,硝基,氰基,C 1 -C 6烷硫基,C 1 -C 6烷基亚磺酰基,C 1 -C 6烷基磺酰基,氨磺酰基,N-(C 1 -C 6烷基)氨磺酰基和N,N-二(C 1 -C 6烷基) 组; (X)n表示在苯环上可以相同或不同的X取代基的数目,其中n为1,2或3.此外,苯并呋喃环上的取代基之一的环己基部分在4,5,6 或7位。 (X)n不能仅用氢气填充,(X)n可以替代环己基部分未被取代的位置; R1选自氢和C1-C4烷基; R2选自C1-C6烷基,C2-C6烯基和C2-C6炔基; R 3选自氢,C 1 -C 6烷基,C 1 -C 6卤代烷基,C 2 -C 6烯基,C 2 -C 6卤代烯基,C 2 -C 6烷氧基烷基,C 2 -C 6烷硫基烷基,苄基和C 2 -C 6卤代烷酰基; R4选自氢,碱金属阳离子,碱土金属阳离子,C1-C4烷酰基,C1-C4卤代烷酰基和苯甲酰基。
