Abstract

Process for the production of azo compounds, of formula I, **(See formula)** where R means a radical of the formula (a), (b), (c), (d), (e), (f) or (g) where it means an amino, anilino or toluidino radical, R2 it means a hydroxy or amino radical, and either R3 means hydrogen, or when R1 and R2 mean amino, R3 means hydrogen, nitro, -SO3H or an alkyl radical of 1 to 6 carbon atoms; **(See formula)** wherein R4 signifies a hydroxy, amino, anilino or toluidino radical, **(See formula)** wherein R5 signifies a hydroxy, C1-C6 alkylsulfonyloxy radical, a phenylsulfonyloxy radical, an amino radical, a C1-C6 alkylsulfonylamino radical, or a phenylsulfonylamino radical, R6 signifies a C1-C6 alkyl, C1-C6 alkoxy, acetyl, carboxyl radical. or carbamoyl, R7 signifies an unsubstituted or substituted acyl radical, or a C1-C6 alkyl, phenyl or naphthyl radical, and H stands for hydrogen or an equivalent of a cation, characterized in that a diazo derivative of a compound of the formula is coupled II, **(See formula)** with a coupling component of formula H-R, where R is defined as above.
