Abstract

Dyestuffs of formula (I) where X1 is the residue of a coupling component of the amino- or hydroxybenzene series, the heterocyclic series, the amino- or hydroxynaphthalene series or with a methylene group capable of coupling, Y is a direct bond or a divalent bridging group, p is 0-3 A is an anion and K1 is where R' and R" are (subst) alkyl or cycloalkyl or together form a heterocyclic group1 R3 and R4 are H, (substituted) alkyl, cycloalkyl or acyl, R8, R9 and R10 are (substituted) alkyl or cycloalkyl or can make a heterocyclic ring as can R' with R3 and/or R" with R4 are prepared by coupling an amine with a coupling component H-X1-Y-K1 circled positive. The dyestuff may be used for paper and polyacrylonitrile textile material.

Description

  

  
 



  Verfahren zur Herstellung von Verbindungen der Dehydrothiotoluidinreihe
Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Verbindungen der Dehydrothiotoluidinreihe der Formel
EMI1.1     
 worin X den Rest einer Kupplungskomponente, n   1 bis 6, und    A den Säurerest eines Esters, vorzugsweise ein Halo genatom, bedeuten und die aromatischen Ringe B und/oder D weitersubstituiert sein können, dadurch gekennzeichnet, dass man eine Verbindung der Formel
EMI1.2     
 nach an sich bekannten Methoden, mit Halogenmethyl abgebenden Verbindungen umsetzt, vorzugsweise chlor   methyliert.   



   Die Ringe B und/oder D können vorteilhaft durch nicht wasserlöslich machende Substituenten substituiert sein.



   Vorzugsweise enthalten sie Halogenatome, die Hydroxy-, Nitro- oder Cyangruppe, gegebenenfalls sub stituierte Alkyl- oder Alkoxygruppen oder Hydroxy aryl- oder Alkoxyarylgruppen. Die Verbindungen (I) können aber auch eine Sulfonsäure- oder Carbonsäure gruppe oder eine Sulfonsäureamid- oder Carbonsäure amidgruppe oder eine Alkyl- oder Arylsulfonylgruppe enthalten.



   Die Kupplungskomponenten gehören beispielsweise der aromatischen Reihe an, z. B. der Benzol- oder
Naphthalinreihe, die einen die Kupplung ermöglichen
Substituenten tragen, z. B. Amino- oder Hydroxy   azole,    Amino- oder Hydroxynaphthaline; aber auch
Kupplungskomponenten der heterocyclischen Reihe, wie der Pyrazolon- oder Aminopyrazolreihe oder der Al kan-, Alken- oder Alkinreihe mit einer kupplungsfähigen Methylengruppe können eingesetzt werden, z. B.

 

     l-Phenyl-3-methyl-pyrazolon-5    und Derivate davon oder Acylessigsäure-aryl- oder alkylamide, usw.



   Die Verbindungen der Formel (I) können als Zwischenprodukte für die Herstellung von Farbstoffen verwendet werden. In den folgenden Beispielen bedeuten die Teile Gewichtsteile und die Prozente Gewichtsprozente. Die Temperaturen sind in Celsiusgraden angegeben.  



   Beispiel
24 Teile 2-(4'-Aminophenyl)-6-methylbenzthiazol werden in salzsaurer Lösung mit 7 Teilen Natriumnitrit diazotiert. Die Diazoniumlösung wird in essigsaurer Lösung mit 15 Teilen 2-Hydroxynaphthalin gekuppelt.



   Die so erhaltene Monoazoverbindung wird in einem Gemisch, bestehend aus 100 Teilen Chlorsulfonsäure und 35 Teilen Schwefelsäure gelöst und mit 20 Teilen Paraformaldehyd versetzt. Man rührt 12 Stunden lang bei   60     und erhält das chlormethylierte Produkt. 



  
 



  Process for the preparation of compounds of the dehydrothiotoluidine series
The invention relates to a process for the preparation of compounds of the dehydrothiotoluidine series of the formula
EMI1.1
 wherein X is the radical of a coupling component, n 1 to 6, and A is the acid radical of an ester, preferably a halogen atom, and the aromatic rings B and / or D can be further substituted, characterized in that a compound of the formula
EMI1.2
 by methods known per se, reacted with halogenomethyl-releasing compounds, preferably chloromethylated.



   The rings B and / or D can advantageously be substituted by non-water-solubilizing substituents.



   They preferably contain halogen atoms, the hydroxyl, nitro or cyano group, optionally substituted alkyl or alkoxy groups or hydroxy aryl or alkoxyaryl groups. The compounds (I) can, however, also contain a sulfonic acid or carboxylic acid group or a sulfonic acid amide or carboxylic acid amide group or an alkyl or arylsulfonyl group.



   The coupling components belong, for example, to the aromatic series, e.g. B. the benzene or
Naphthalene series that enable a coupling
Carry substituents, e.g. B. amino or hydroxy azoles, amino or hydroxynaphthalenes; but also
Coupling components of the heterocyclic series, such as the pyrazolone or aminopyrazole series or the alkane, alkene or alkyne series with a methylene group capable of coupling can be used, for. B.

 

     l-phenyl-3-methyl-pyrazolone-5 and derivatives thereof or acyl acetic acid aryl or alkyl amides, etc.



   The compounds of the formula (I) can be used as intermediates for the preparation of dyes. In the following examples, the parts are parts by weight and the percentages are percentages by weight. The temperatures are given in degrees Celsius.



   example
24 parts of 2- (4'-aminophenyl) -6-methylbenzthiazole are diazotized in hydrochloric acid solution with 7 parts of sodium nitrite. The diazonium solution is coupled with 15 parts of 2-hydroxynaphthalene in acetic acid solution.



   The monoazo compound thus obtained is dissolved in a mixture consisting of 100 parts of chlorosulfonic acid and 35 parts of sulfuric acid, and 20 parts of paraformaldehyde are added. The mixture is stirred for 12 hours at 60 and the chloromethylated product is obtained.
