    Abstract: The invention relates to compounds of the general formula I where X is hydrogen, C1-C4-alkyl or -alkoxy, chlorine, bromine or chlorine-, bromine-, methyl- or methoxy-substituted phenyl, benzyl, phenoxy or phenylmercapto, Y is cyano, carboxylic ester or substituted carboxamide, Z is formyl or a radical -CH=R, where R is the radical of an active-methylene compound, R is hydrogen or R , and R is optionally substituted alkyl or aryl. The compounds of the invention are very highly suitable for dyeing textile material made of polyesters or colouring thermoplastics.

    Abstract: The invention relates to a process for the preparation of compounds which in one of the possible tautomeric forms and as free acidic compounds correspond to the general formula I in which R is an optionally substituted alkyl, alkoxy, cycloalkoxy or aroxy radical and in which the ring A can also be substituted, which is characterised in that compounds of the formula II in which X is hydrogen or an alkoxycarbonyl group and R, with the exception of optionally substituted alkyl, has the meaning indicated, are reacted in alkoxide-containing solution and then acidified. The compounds prepared according to the invention are useful precursors for the preparation of dyestuffs.

    Abstract: Compounds of the general formula I where X is unsubstituted or substituted alkyl, cycloalkyl, aralkyl or aryl, Y is chlorine, bromine, carbamyl or cyano, Z is hydrogen, carbamyl, cyano or acetyl, R is hydrogen or C1-C3-alkyl, R1 and R3 independently of one another are each hydrogen or unsubstituted or substituted alkyl, alkenyl, cycloalkyl, aralkyl or aryl, R2 is hydrogen or unsubstituted or substituted alkyl and R1 and R2, together with the nitrogen atom, form a saturated 5-membered or 6-membered ring, are particularly useful for dyeing textile fibers.
