wherein A is hydrogen or one of a specified range of substituents e.g. halogen, hydroxy, haloalkyl, B, C, E and F are hydrogen or specified substituents; D is CF3, halogen, or another specified substituent; and R is a group -CONR4SO2R3 wherein R4 is hydrogen or C, to C. alkyl and R' is an optionally substituted alkyl, alkenyl, alkynyl, or aryl radical; useful as selective herbicides.
式中 A 是氢或指定范围的取代基之一,如卤素、羟基、卤代烷基;B、C、E 和 F 是氢或指定的取代基;D 是 CF3、卤素或另一个指定的取代基;R 是一个基团-CONR4SO2R3,其中 R4 是氢或 C 至 C.烷基,R'是任选取代的烷基、烯基、炔基或芳基;可用作选择性除草剂。
