BENZENESULFONYLUREA DERIVATIVES

摘要

The present invention relates to novel benzenesulfonylurea derivatives, having a herbicidal activity, which is described in the structure of general formula (I), wherein R<1> is H, C1-C3 alkyl, C1-C3 haloalkyl, halogen, CN, NO2, C1-C3 alkoxy, C1-C3 haloalkoxy, SO2NRR, 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 CO2R; and then R is H, C1-C4 alkyl, C2-C3 cyanoalkyl, methoxy or ethoxy; R is H, C1-C4 alkyl, C3-C4 alkenyl, or when taken together connecting R and R, -(CH2)3-, -(CH2)4-, -(CH2)5- or CH2CH2OCH2CH2-, may be formed; R is C1-C4 alkyl, C3-C4 alkenyl, C3-C4 alkynyl, C1-C4 alkyl substituted with 1 SIMILAR 3 halogens or cyano groups, C5-C6 cycloalkyl, C3-C7 cycloalkylalkyl or C2-C4 alkoxyalkyl; R<2> is C1-C6 alkyl substituted with 1 SIMILAR 3 halogens; R<3> 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.
