The present invention relates to novel benzenesulfonylurea derivatives, having a herbicidal activity, which is described in the structure of general formula (I), wherein RI is H, C1-C3 alkyl, C1-C3 haloalkyl, halogen, CN, NO2, C1-C3 alkoxy, C1-C3 haloalkoxy, SO2NRIRII, C1-C3 alkylthio, C1-C3 alkylsulfinyl, C1-C3 alkylsulfonyl,: SCH2F, NH2, NHCH3, N(Me)2, C1-C2 alkyl substituted with C1-C2 alkoxy, C1-C2 haloalkoxy, SH, SCH3, CN or OH, or CO2RIII; and then RI is H, C1-C4 alkyl, C2-C3 cyanoalkyl, methoxy or ethoxy; RII is H, C1-C4 alkyl, C3-C4 alkenyl, or when taken together connecting RI and RII, -(CH2)3-, -(CH2)4-, -(CH2)5- or CH2CH2OCH2CH2-, may be formed; RIII is C1-C4 alkyl, C3-C4 alkenyl, C3-C4 alkynyl, C1-C4 alkyl substituted with 1 ~ 3 halogens or cyano groups, C5-C6 cycloalkyl, C3-C7 cycloalkylalkyl or C2-C4 alkoxyalkyl; R2 is C1-C6 alkyl substituted with 1 ~ 3 halogens; R3 is H or CH3; W is O or S; A is a heterocyclic ring defined in the specification; and these may be an agriculturally suitable salt.

Nouveaux dérivés de benzènesulfonylurée, herbicides; ils correspondent à la formule générale (I), où RI représente H, un alkyle C1-C3, un haloalkyle C1-C3, un halogène, CN, NO2, un alcoxy C1-C3, un haloalcoxy C1-C3, SO2NRIRII, un alkylthio C1-C3, un alkylsulfinyle C1-C3, un alkylsulfonyle C1-C3, SCH2F, NH2, NHCH3, N(Me)2, un alkyle C1-C2 avec substitution par un alcoxy C1-C2, un haloalcoxy C1-C2, SH, SCH3, CN ou OH ou CO2RIII; ensuite RI représente H, un alkyle C1-C4, un cyanoalkyle C2-C3, un méthoxy ou un éthoxy; RII représente H, un alkyle C1-C4, un alcényle C3-C4, ou lorsqu'ils sont pris ensemble liant RI et RII, -(CH2)3-, -(CH2)4-, -(CH2)5- ou CH2CH2OCH2CH2- peuvent être formés; RIII représente un alkyle C1-C4, un alcényle C3-C4, un alcynyle C3-C4, un alkyle C1-C4 avec substitution par 1 ~ 3 halogènes ou groupes cyano, un cycloalkyle C5-C6, un cycloalkylalkyle C3-C7 ou un alcoxyalkyle C2-C4 ; R2 est un alkyle C1-C6 avec substitution par 1 ~ 3 halogènes; R3 représente H ou CH3; W représente O ou S; A est un hétérocycle défini dans la spécification; ces produits peuvent être des sels utiles en agriculture.
