Abstract

Trifluoromethylarylsulphonic acids, -sulphonamides and -sulphones of the formula I <IMAGE> in which the substituents are defined in Claim 1, are prepared. These compounds are obtained by a chemically original process in which corresponding o- or p-haloarylsulphonyl compounds are reacted in non-aqueous solvents with ammonia under pressure and at elevated temperature. The said compounds can be used to prepare azo dyes by diazotisation and coupling to coupling components.
