Sulfur compounds useful for preparation of dyes

A process for preparing pyridones of the formula I ##STR1## where R.sup.1 is hydrogen, C.sub.1 -C.sub.6 -alkyl, C.sub.3 -C.sub.7 -cycloalkyl, C.sub.3 -C.sub.4 -alkenyl or substituted or unsubstituted phenyl, R.sup.2 is cyano, carbamoyl, carboxyl, C.sub.1 -C.sub.6 -alkoxycarbonyl, substituted or unsubstituted C.sub.1 -C.sub.6 -alkanoyl, substituted or unsubstituted benzoyl, halogen or nitro, R.sup.3 is hydrogen, and R.sup.4 is substituted or unsubstituted C.sub.1 -C.sub.12 -alkanoyl, C.sub.1 -C.sub.12 -alkoxycarbonyl, substituted carbamoyl, substituted or unsubstituted C.sub.1 -C.sub.12 -alkylsulfonyl, C.sub.5 -C.sub.7 -cycloalkylsulfonyl, substituted or unsubstituted arylsulfonyl or hetarylsulfonyl, substituted or unsubstituted arylcarbonyl or hetarylcarbonyl, or R.sup.3 and R.sup.4 together with the nitrogen atom joining them together are a heterocyclic radical, comprises reacting the carbonyl compounds of the formulae II and III ##STR2## where Y is oxygen or imino and one of the radicals X.sup.1 and X.sup.2 is a radical of the formula NH--NR.sup.3 R.sup.4 and the other is C.sub.1 -C.sub.6 -alkoxy, and R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are each as defined above, in a diluent in the presence or absence of a base.

Preparation of N-aminopyridones

The compounds of the general formula I ##STR1## where X is fluorine, chlorine, bromine, SO.sub.2 E or unsubstituted or substituted hydroxyl or mercapto, E is alkyl, alkenyl, cycloalkyl, aralkyl, aryl, chlorine or unsubstituted or substituted hydroxyl or amino, Y is cyano, nitro, alkanoyl, aroyl, alkylsulfonyl, arylsulfonyl, carboxyl, a carboxylic ester group or unsubstituted or substituted carbamyl, T is hydrogen, C.sub.1 -C.sub.4 -alkyl, a radical which can be introduced by electrophilic substitution or a radical of the formula --CH.dbd.B, in which B is a radical of a methylene-active compound or of an amine, and K is a radical of a coupling component, are very useful for dyeing synthetic fibers or plastics.
