Verfahren zur Darstellung von Indophenolen.
In der Stammpatentschrift Nr. 56760 ist ein Verfahren zur Darstellung neuer Indophenole beschrieben, welche darin besteht, dass das sogenannte Perimidin und seine Derivate entweder mit p Aminophenol oder dessen Derivaten zusammenoxydiert werden oder dass man diese Verbindungen mit Chinoncblorimid oder dessen Derivaten kondensiert.
Es wurde nun gefunden, dass auch andere ähnlich konstituierte, vom 1.8-Naphtylendiamin sich ableitende Verbindungen zur Darstellung von Indophenolen befähigt sind. So kann man beispielsweise das Dihydrothioperimidon-2 durch Kondensation mit Chinonchlorimid in ein Indophenoi überführen ; desgleichen lässt sich die aus dem 1.8-Naphtylendiamin erhältliche Azimidoverbindung, z. B. durch Kondensation mit Dichlorchinonchlorimid, zum Indophenol kondensieren.
Zur Erläuterung des Verfahrens seien folgende Beispiele gegeben.
1. 20 Gewichtsteile Dihydrothioperimidon-2, die in zirka 500 Teilen Wasser suspendiert sind, werden mit 15 Teilen Natronlauge von 400 Bé und dann unter Rühren mit 14'2 Teilen Cbinonchlorimid versetzt. Es bildet sich eine tiefgrünlich-blau gefärbte Lösung, aus der sich das gebildete Indophenol durch Zusatz von Säuren in Gestalt rotbrauner Flocken abscheiden lässt.
2. Die Darstellung eines Indophenols aus dem Körper
EMI1.1
(vgl. Lieb. Annalen, 365, Seite 59) und Dichlorchinonchlorimid gestattet sich beispielsweise wie folgt :
17 Teile der aus 1. 8-Naphtylendiamin erhältlichen Aziminoverbindung werden, wie in Beispiel 1 angegeben, mit 21#1 Teilen Dichlorchinonchlorimid kondensiert; man erhält eine grünblau gefärbte Lösung, aus der das gebildete Indophenol durch Zusatz von Säuren m Form braunvioletter Flocken ausgeschieden werden kann.
An Stelle der in den vorstehenden Beispielen verwendeten Abkömmlinge des 1.8-Naphtylendiamins kann man auch ähnlich konstituierte Verbindungen, wie z. B. das DihydroperInldon-2, in Reaktion bringen.

Process for the preparation of indophenols.
In the parent patent specification No. 56760 a process for the preparation of new indophenols is described, which consists in that the so-called perimidine and its derivatives are either oxidized together with p-aminophenol or its derivatives or that these compounds are condensed with quinone chlorimide or its derivatives.
It has now been found that other similarly constituted compounds derived from 1,8-naphthylenediamine are also capable of preparing indophenols. For example, dihydrothioperimidone-2 can be converted into an indophenoi by condensation with quinone chlorimide; the azimido compound obtainable from 1,8-naphthylenediamine, e.g. B. by condensation with dichloroquinone chloride to condense to the indophenol.
The following examples are given to explain the process.
1. 20 parts by weight of dihydrothioperimidone-2, which are suspended in about 500 parts of water, are mixed with 15 parts of sodium hydroxide solution of 400 Be and then with stirring with 14.2 parts of Cbinonchlorimid. A deep greenish-blue colored solution is formed, from which the indophenol formed can be separated in the form of red-brown flakes by adding acids.
2. The representation of an indophenol from the body
EMI1.1
(cf. Lieb. Annalen, 365, page 59) and dichloroquinone chlorimide are permitted, for example, as follows:
17 parts of the azimino compound obtainable from 1,8-naphthylenediamine are, as indicated in Example 1, condensed with 21 parts of dichloroquinone chlorimide; a green-blue colored solution is obtained from which the indophenol formed can be excreted in the form of brownish-violet flakes by adding acids.
Instead of the derivatives of 1,8-naphthylenediamine used in the preceding examples, compounds with a similar constitution, such as. B. the DihydroperInldon-2, bring into reaction.
