ABSTRACT:
Intermediates useful for the preparation of fiber-reactive dyes having the formula ##STR1## in which Q is phenyl unsubstituted or substituted by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, nitro, cyano, C.sub.1 -C.sub.4 alkoxycarbonyl, C.sub.1 -C.sub.4 alkylsulfonyl, sulfo or trihalomethyl; 1- or 2-naphthyl; or unsubstituted or C.sub.1 -C.sub.4 alkyl, nitro, cyano, C.sub.1 -C.sub.4 alkoxycarbonyl or C.sub.1 -C.sub.4 alkylthio substituted furanyl, thienyl, thiazolyl, oxazolyl, isothiazolyl, benzothiazolyl, benzoisothiazolyl, pyrazolyl, imidazolyl, 1,2,3-triazolyl, 1,2,4-triazolyl, 1,2,4-thiadiazolyl, 1,3,4-thiadiazolyl or 1,3,5-triazinyl, and A.sub.1 and A.sub.2 independently of one another are a radical of the formula ##STR2## in which R.sub.1 and R.sub.2 independently of one another are hydrogen; C.sub.1 -C.sub.4 alkyl unsubstituted or substituted by hydroxyl, sulfo, sulfato, carboxyl, cyano, halogen, C.sub.1 -C.sub.4 alkoxycarbonyl, C.sub.1 -C.sub.4 alkanoyloxy or carbamoyl and uninterrupted or with the exception of methyl interrupted by --O-- or --NR.sub.4 -- wherein R.sub.4 is hydrogen or C.sub.1 -C.sub.4 alkyl, or naphthyl or phenyl each of which is unsubstituted or substituted by sulfo, carboxyl, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen or a group --N.dbd.N--K wherein K is a coupling component benzene, naphthalene or heterocyclic radical; or R.sub.1 and R.sub.2 together with the N atom form a piperidinyl, piperazinyl or pyrrolidinyl radical, with the proviso that at least one of the radicals A.sub.1 or A.sub.2 is further substituted by a fiber-reactive radical.
