Diacarbamoylverbindungen

摘要

Dicarbamoyl compounds of general formula (I) wherein: m is 1 or 2, n is 0, 1 or 2, W if necessary C2 to C4 alkylene is substituted by C1 to C4 alkyl, chlorine, bromine or phenyl or phenylene optionally substituted by methyl, ethyl, methoxy, ethoxy, hydroxy, chlorine, bromine, hydroxysulfonyl, nitro, amino, acetalamino, or carboxyl; X is C2-C8 alkylene interrupted one to three times, optionally substituted by ether oxygen, imino, phenylimino or C1 to C4 alkylamino or a residue of the formula (II); Z is a residue of formula (III) or (IV); R is hydrogen, C1 to C4 alkyl, phenyl, CH2CH2OH, CH2CH2OSO3H, CH2CH2SO3H or a residue of formula (V); L<1> and L<2> are independently C1 to C4 alkylenes; Y is vinyl or a residue of the formula C2H4Q where Q means hydroxy or a residue separable under alkalic reaction conditions; and Ar means phenyl or naphthyl and both residues can be substituted one to three times by C1-C6 alkyl, C1-C6 alkoxy, fluorine, chlorine, bromine, nitro, amino, hydroxy, hydroxysulfonyl, carboxyl, C1 to C6 alkoxycarbonyl, acetylamino, a residue of formula (VI), (VII), SO2NH-X-S(O)n-Y or S(O)n-Y where R<1> and R<2> are independently hydrogen or C1 to C6 alkyl and n, X and Y have the given meaning. The invention also relates to the use of these compounds for the preparation of fiber reactive dyes.
