Abstract

Abstract N-(heterocyclicaminocarbonyl)arylsulfonamides, such as 3-isocyanato-N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)aminocarbonyl]benzenesulfonamide or methyl [3-[[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]aminosulfonyl]phenyl]carbamate, are useful for the regulation of plant growth and as herbicides.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 124 words
A compound or an agriculturally acceptable salt thereof which has the formula: ##STR155## wherein R 1 is H, Cl, Br, F, CH 3 , OCH 3 or NO 2 ; R 2 is --NCO, ##STR156## R 3 is alkyl of 1-4 carbon atoms; R 4 is H or CH 3 ; R 5 is H, alkyl of 1-4 carbon atoms or methoxy; X is methyl, methoxy or ethoxy; Y is methyl or methoxy; and Z is N; provided that (a) when R 2 is ortho to the sulfonylureido group, then R 1 must be hydrogen and R 2 cannot be --NCO; (b) when R 5 is methoxy, R 4 is methyl; and (c) when R 2 is --NCO; the compound cannot be a salt.
Claim 2
Dependent Claim 124 words
A compound or an agriculturally acceptable salt thereof which has the formula: ##STR155## wherein R 1 is H, Cl, Br, F, CH 3 , OCH 3 or NO 2 ; R 2 is --NCO, ##STR156## R 3 is alkyl of 1-4 carbon atoms; R 4 is H or CH 3 ; R 5 is H, alkyl of 1-4 carbon atoms or methoxy; X is methyl, methoxy or ethoxy; Y is methyl or methoxy; and Z is N; provided that (a) when R 2 is ortho to the sulfonylureido group, then R 1 must be hydrogen and R 2 cannot be --NCO; (b) when R 5 is methoxy, R 4 is methyl; and (c) when R 2 is --NCO; the compound cannot be a salt.
