摘要：
Compounds of formula (I) or salts thereof, wherein R1-R4, W, A, n and m are defined as in claim 1, e.g. R1, R2 represent H, (subst.) alkyl, (subst.) alkenyl or alkinyl, (subst.) cycloalkyl, (subst.) aryl or acyl, and A represents (subst.) pyrimidinyl or triazinyl, are suitable for use as selective sulphonyl urea herbicides and plant growth regulators. The process for the production of (I) is analogous with known processes, while some of the intermediate products involved are novel, for example the appropriately substituted pyridyl sulphonamides (II) and N-tert.-butyl sulphonamides (VIII) disclosed in claim 5.
