Sulfonamide derivatives of formulae <CHEM> wherein Q is selected from various 5 and 6-membered heterocyclic groups, which are optionally substituted, Q min is selected from various 6-membered nitrogen-containing heterocyclic groups, which are optionally substituted, R1 is H, F, Cl, Br, CH3, CF3 or OCH3, R17 is H or CH3, W is O or S, A is a substituted heterocyclic moiety, X is CH3, OCH3 or Cl, Y is amino or various organic groups, Z is CH or H; and their agriculturally suitable salts exhibit herbicidal and plant growth regulant effects. The compounds may be formulated for agricultural use in conventional manner. The compounds may be prepared by a variety of routes, e.g. by reacting an appropriately substituted benzene-sulfonamide having a Q or Q min moiety in the 2-position with a methyl carbamate of the appropriate heterocylic amine, under catalytic conditions. |
