Abstract: Iso-thiourea derivatives containing sulpho-acid groups are prepared by reacting a sultone with thiourea or a nitrogen-substituted thiourea which has at least one hydrogen atom attached to a thiourea nitrogen atom but is unsubstituted on the sulphur atom.  Those of the nitrogen-substituted thioureas which are tautomeric may be reacted in the form of a metal salt of the compound.  Reaction may be effected in the presence of water or an organic solvent or the reactants may be ground together and then heated.  Suitable thiourea reagents have the general formula <FORM:0775026/IV(b)/1> wherein R1, R2 and R3 each represent a hydrogen atom or hydrocarbon residue; also R1 and R2 or R1 and R3 may belong to a common heterocyclic ring system; R1, R2, R3 or R1 and R3 may also represent amino or amino groups or acyl groups of carboxylic acids; finally, the hydrocarbon residues or acyl, amino or imino groups may be substituted and the hydrocarbon residues or acyl groups may be broken, by hetero atoms or groups of atoms.  The substituted thioureas reacted in the form of their thiolic salts yield sulphonic acid salts and the other thioureas yield sulpho-betaine-type compounds.  In examples, propane-sultone is reacted with (1) thiourea, (3) N-phenyl thiourea, (4) p-tolyl thiourea, (5) N : N1-diphenyl thiourea, (6) 4-methyl-thiouracil sodium salt, (7) dithizone sodium salt, (8) benzaldehyde-thiosemicarbazone sodium salt, the resulting sulphonate on acidifying yielding the free sulphonic acid, (9) p-methoxy benzaldehyde-thiosemicarbazone sodium salt, (10) ethylene thiourea and (11) phenylene-thiourea sodium salt; (2) thiourea is reacted with 1 : 4-butane sultone.  Several other reagents are specified including N-dodecyl thiourea, N-acetyl thiourea, thiosemicarbazide, and thiobarbituric acid and isopentane sultone, tolyl sultone and 1 : 8-naphthsultone.
