Sulfonamides of the general formula I ##STR1## where A, n, R.sup.1, R.sup.2, R.sup.3, W, X, Y and Z have the meanings given in the disclosure and claims, salts and N-oxides thereof, and their use as herbicidal agents.

Heterocyclic sulfonamides

Sulfonamides

New and valuable O-substituted glycolic acid anilides having a good herbicidal action, a process for their manufacture, herbicides containing these new compounds as active ingredients, and a process for controlling the growth of unwanted plants with these active ingredients.

Substituted O-alkylsulfonylglycolic acid anilides

Reaction of 1-hydroxy-2-ketones of the general formula R-- CO-- CH.sub.2 OH, where R is a short alkyl, with ammonia gives a new compound ##STR1## which on hydrogenation gives 2-amino-1-alcohols; the yield can be improved by carrying out the hydrogenation in the presence of ammonia.
