摘要:
Diphenyl ethers of formula: 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 CF 3 , halogen, or another specified substituent; and R is a group -CONR 4 SO 2 R 3 wherein R 4 is hydrogen or C, to C. alkyl and R' is an optionally substituted alkyl, alkenyl, alkynyl, or aryl radical; useful as selective herbicides.
摘要:
Compounds of the formula (I): wherein A is hydroxy, lower alkoxy, mercapto, lower alkylthio, alkylsulphinyl or alkylsulphonyl, or lower mono- or dialkylamino, methyl, or trifluoromethyl: B is fluorine or chlorine: C and E are hydrogen: D is trifluoromethyl; and F is hydrogen, chlorine, or fluorine, and salts, esters and amides thereof. The compounds are useful as herbicides.
摘要:
Phosphonic acid derivatives of the formula (I) wherein R 1 and R 2 are each hydrogen, a cation or an optionally substituted alkyl, alicyclic, or phenyl radical; R 3 is hydrogen or alkyl; and R 4 may be H, OH, F, NH 2 , optionally substituted alkoxy, alkenyloxy or alkynyloxy, or a range of specified acyloxy radicals, or R 3 and R 4 with the adjacent carbon atom may form a keto group or a functional derivative thereof. The compounds are useful as herbicides.
