Abstract
The invention comprises trifluoromethyl benzenesulphonamides of the formula <FORM:0899584/IV (b)/1> wherein A is hydrogen, nitro or amino. The nitro derivative is prepared by reacting a 2-nitro-4-trifluoromethylhalobenzene with sodium sulphide and treating the resulting bis-(2-nitro-4-trifluoromethylphenyl) disulphide with chlorine in aqueous acetic acid to give 2-nitro-4-trifluoromethylbenzenesulphonyl chloride which is converted to the sulphonamide by treatment with ammonia. The product wherein a is an amino group is prepared by reducing the nitro compound; the amino group may then be split off by diazotising, heating to reflux, neutralizing with sodium hydroxide, and treating with phosphorus oxychloride to give 4-trifluoromethylbenzenesulphonyl chloride which is converted to the sulphonamide by treatment with ammonium carbonate.
