Abstract

Process for the manufacture of new benzolsulfonyl-semicarbazides, characterized in that those of the general formula ** (See formula) ** where they mean: n number 1 or 2, R1 and R2 hydrogen, halogen, alkyl, alkenyl, alkoxy, alkenoxy, alkylmercapto, acyl, azido or trifluoromethyl, To a methylene group (> CH2), a carbonyl group (> CO) or a hydroxymethylene group (> CHCH), which may be etherified or esterified, and their salts, are obtained by reacting with each other, suitable methods, benzolsulfonyl compounds of the formula ** (See formula) ** with compounds of the formula ** (See formula) ** wherein one of both X and Y moieties means an amino group, while the other is an isocyanate group, or a moiety which under the reaction conditions can be transferred to an isocyanate group; or alternatively substituted benzolsulfonyl-thiosemicarbazides are transferred ** (See formula) ** or benzolsulfonylaminoguanidines ** (See formula) ** or benzolsulfonyl isosemicarbazide ethers ** (See formula) ** by appropriate hydrolytic measurements, to the corresponding benzolsulfonyl-semicarbazides, it being also planned to react benzolsulfonyl-halides of the formula ** (See formula) ** with semicarbazides of the formula ** (See formula) ** or with the corresponding parabenic acid derivatives, and the intermediates obtained are hydrolyzed, after which the formation of salt eventually occurs.
