Process for the manufacture of new benzolsulfonyl-semicarbacids, characterized in that from those of the general formula ** (See formula) ** wherein R1 is halogen and Z is an alkylene group having 3 to 5 carbon atoms, which may be substituted one or more times by lower alkyl radicals; and of its salts, benzolsulfonyl combinations of the formula are reacted by suitable methods ** (See formula) ** with combinations of the formula ** (See formula) ** wherein one of the X and Y moieties always means an amino group, while the other is an isocyanate group or a moiety transferable to an isocyanate group under the reaction conditions, each other or to the correspondingly substituted benzolsulfonyl-thiosemicarbacides ** (See formula) ** or benzolsulfonylaminoguanidines ** (See formula) ** or benzolsulfonyl isosemicarbazide ethers ** (See formula) ** they are transferred, under appropriate hydrolytic conditions, to the corresponding benzolsulphonyl-semicarbacids, the possibility of reacting benzolsulfonylhalogenides of the formula having also been provided ** (See formula) ** with semicarbacidas of the formula ** (See formula) ** or with the corresponding pranic acid derivatives hydrolyzing the obtained intermediate products, after which a salt formation is optionally produced.
