This invention relates to substituted diphenyl ethers having selective herbicidal properties and having the formula:
wherein R is a saturated or unsaturated, straight chain or branched aliphatic hydrocarbon radical of from 1 to 18 carbon atoms wherein one or more of the -CH2- groups can be replaced with -0-, -S-, -S-S-, -SO-, -S02- or -NR2- and said hydrocarbon radical is optionally substituted with halogen, trihalomethyl, cyano, aryl, hydroxy, alkoxy, nitro or cycloalkyl having 3 to 6 carbon atoms;
R2 is hydrogen or a saturated or unsaturated straight or branched chain aliphatic radical having from 1 to 8 carbon atoms, optionally substituted with halogen, hydroxy, alkoxy, cyano or nitro:
R4 and R5 are independently a saturated or unsaturated, straight or branched chain aliphatic radical having 1 to 8 carbon atoms optionally substituted with halogen, trihalomethyl, alkoxy or cyano; hydrogen or phenyl optionally substituted with halogen, alkyl, alkoxy, trihalomethyl, nitro or cyano;
L, M and N are each independently hydrogen, hydroxy, halogen, trihalomethyl, nitro, cyano, alkyl or alkoxy having from 1 to 4 carbon atoms and
本发明涉及具有选择性除草特性的取代二苯醚,其式如下
其中 R 是 1 至 18 个碳原子的饱和或不饱和、直链或支链脂肪族烃基,其中一个或多个 -CH2- 基团可被 -0-、-S-、-S-S-、-SO-、-S02- 或 -NR2- 取代,并且所述烃基任选被卤素、三卤甲基、氰基、芳基、羟基、烷氧基、硝基或具有 3 至 6 个碳原子的环烷基取代;
R2 是氢或具有 1 至 8 个碳原子的饱和或不饱和直链或支链脂肪族基,可选择被卤素、羟基、烷氧基、氰基或硝基取代:
R4 和 R5 独立地是具有 1 至 8 个碳原子的饱和或不饱和直链或支链脂肪族基,可选地被卤素、三卤甲基、烷氧基或氰基取代;氢或苯基,可选地被卤素、烷基、烷氧基、三卤甲基、硝基或氰基取代;
L、M 和 N 各自独立地是氢、羟基、卤素、三卤甲基、硝基、氰基、具有 1 至 4 个碳原子的烷基或烷氧基,以及
