New N-(3-(alkylsulfonylamino)-phenyl)-phthalimide and N-(3-(arylsulfonylamino)-phenyl)-phthalimide derivatives useful as herbicides, especially for selective weed control in crops

摘要

N-Sulfonylaminophenyl-phthalimide derivatives (I) are new. N-(3-((Alkyl or aryl)sulfonylamino)-phenyl)-phthalimide derivatives of formula (I) are new: R1 = H; NO2; CN; or halo; R2 = OH; NO2; CN; thiocarbamoyl; halo; or optionally substituted alkyl or alkoxy; R3 = H; or optionally substituted alkyl, alkylsulfonyl, alkylcarbonyl, arylcarbonyl, aralkylcarbonyl or aryloxycarbonyl; R4 = optionally substituted alkyl or aryl; X = NO2; NH2; halo; or optionally substituted alkyl or alkoxy; n = 0-4. An Independent claim is also included for the preparation of (I).
