Abstract

Aryl sulphonyl thioureas and nuclear substitution products thereof are obtained by treating the corresponding aryl sulphonyl cyanamides with hydrogen sulphide. Substituent groups which are mentioned are amino and acylamino groups. In examples: (1) a pyridine solution of p-aminobenzenesulphonyl cyanamide is saturated with hydrogen sulphide, the pyridine removed and the product purified with carbon black in sodium carbonate solution. The p-aminobenzenesulphonyl thiourea is precipitated with acetic acid; (2) an aqueous ammonia solution of p-aminobenzenesulphonyl cyanamide is treated with hydrogen sulphide and purified as in example (1); (3) as in example (2) using alcohol as solvent; (4) a pyridine solution of the sodium salt of p-acetylaminobenzenesulphonyl cyanamide is saturated with hydrogen sulphide and the product treated with caustic soda to hydrolyse the acetylamino group; (5) as in example (4), but using the sodium salt of benzene sulphonyl cyanide. The compounds of this invention are stated to possess bactericidal and anti-mycosic properties.
