Abstract: The present invention discloses substituted phenyl di and trisazo dyes free of reactive groups having two or three sulfonic acid groups, of the general formula: (I) wherein D1 is Z is hydrogen or D4-N=N-; D2 is phenyl substituted by hydroxyl, hydroxysulfonyl, chlorine or nitro, or is naphthyl substituted by hydroxy, hydroxysulfonyl or nitro, X, independently of one another, are hydroxyl or amino, D3 is phenyl which is substituted by hydroxysulfonyl, chlorine, bromine, methyl, methoxy, ethoxy, nitro, phenylamino, sulfophenylamino or nitrosulfophenylamino, or is naphthyl which is substituted by hydroxysulfonyl; D4 is phenyl which is unsubstituted or substituted by methyl, ethyl, methoxy, ethoxy, chlorine, bromine, nitro, sulfamoyl or hydroxysulfonyl, or is naphthyl which is substituted by hydroxysulfonyl; and R2 is methyl, ethyl or allyl; the rings B and E may additionally be substituted by methyl, ethyl, methoxy, ethoxy, chlorine, bromine or hydroxysulfonyl, with the proviso that D2 has a hydroxyl group ortho to the azo bond; or the iron, manganese, cobalt, chromium, nickel or copper complexes of this dye. These compounds, particularly in the form of their metal complexes are suitable for dyeing nitrogen-containing fibers such as wool, and preferably, leather. The present dyes yield very fast brown hues, in particular on retanned leather.

Abstract: The invention relates to a process for the preparation of isomer-free N-alkylsulphonylphenylenediamines of the general formula I in which R denotes hydrogen or optionally substituted C1-C6-alkyl, and R denotes optionally substituted alkyl, alkenyl, aralkyl or cycloalkyl, or a radical of the formula in which R and R are alkyl groups or, together with the nitrogen atom, form a 5-membered or 6-membered ring which is optionally interrupted by a heteroatom, characterised in that compounds of the general formula II in which R has the abovementioned meaning, are selectively reacted with a sulphonyl halide of the formula III in which R has the abovementioned meaning and Hal represents fluorine, chlorine or bromine, in the presence of an alkaline earth metal oxide or carbonate at a pH of 3 to 7, and in the presence of a diluent, at temperatures of from -20 to +40 DEG C. The compounds prepared according to the invention are highly suitable for use as diazo components.

Abstract: The invention relates to a process for the preparation of compounds of the formula I in which the substituents Hal, independently of one another, are chlorine or bromine, and the ring A may be substituted, which is characterised in that compounds of the formula II in which Hal is as defined above, and n may be 0, 1 or 2, are reacted at elevated temperature with a chlorinating agent in solvents which cannot be halogenated under the reaction conditions. The compounds obtained from the process are suitable as redox catalysts or dye precursors.

Abstract: The invention relates to a process for the preparation of compounds of the formula in which the substituents X, Y, R and R have the customary meanings in dyestuff chemistry and m is 1 or 2, which process is characterised in that compounds of the formula in which m, R , X and Y have the given meaning, are reacted with a sulphonyl halide of the formula Hal-SOR in which R has the abovementioned meaning and Hal represents fluorine, chlorine or bromine, in the presence of a tertiary organic nitrogen base having a pka value of 2.0 to 8.5 and in the presence of a diluent, which can also be the organic nitrogen base itself, at temperatures of from 0 to 200 DEG C.

Abstract: The invention relates to novel sulphonamides of the general formula I in which R denotes hydrogen, alkali metal, optionally substituted ammonium or optionally substituted alkyl, and R denotes optionally substituted alkyl, alkenyl, aralkyl or cycloalkyl, or a radical of the formula in which R and R are alkyl groups or, together with the nitrogen atom, form a 5-membered or 6-membered ring which is optionally interrupted by a heteroatom. The compounds according to the invention are very suitable for use as diazo components.
