Verfahren zur Darstellung von Derivaten kernmercurierter Phenole.
Es wurde gefunden, dass man zu Derivaten kernmercurierter Oxyverbindungen dadurch gelangen kann, dass man die Mercurierung der Oxyverbindungen bei Gegenwart solcher Verbindungen, welche die Reste der Rhodan-, Ferrocyan-oder Ferricyanwasserstoffsäure enthalten, in üblicher Weise vornimmt, d. h. z. B. durch Kochen mit Quecksilberoxyd in alkalischer Lösung. Man erhält so Produkte. welche für bakterizide, fungizide und sonstige pharmazeutische Zwecke Verwendung finden sollen.
Beispiel 1 : Aus 54 Gewichtsteilen Sublimat durch Fällen mit Natronlauge hergestelltes Quecksilberoxyd wird abfiltriert, ausgewaschen, bis das Filtrat nicht mehr alkalisch reagiert, in 50 Gewichtsteilen Wasser suspendiert und 22 Gewichtsteile o-Kresol sowie die zur Lösung des letzteren gerade erforderliche Menge Natronlauge hinzugefügt. Unter kräftigem Rühren werden 20 Gewichtsteile Rhodankalium zugesetzt und einige Stunden auf etwa 70-900 erwärmt, wobei unter Bildung der kernmercurierten Rhodanverbindung Lösung des Quecksilberoxyds erfolgt.
Man filtriert sodann von kleinen Resten

- Beispiel 2 : 27 Gewichtsteile Sublimat werden, wie im Beispiel 1 angegeben, in frisch gefälltes Quecksilberoxyd übergeführt, 11 Gewichtsteile o-Kresol hinzugefügt und diese mit der gerade genügenden Menge Natronlauge in Lösung gebracht ; hierauf werden 5 Gewichtsteile rotes Blutlaugensalz hinzu-

Process for the preparation of derivatives of nuclear mercured phenols.
It has been found that derivatives of nucleus mercurated oxy compounds can be obtained by carrying out the mercuration of the oxy compounds in the presence of compounds which contain the radicals of rhodanic, ferrocyanic or ferricyanic acid in the usual manner; H. z. B. by boiling with mercury oxide in an alkaline solution. This is how you get products. which are to be used for bactericidal, fungicidal and other pharmaceutical purposes.
Example 1: Mercury oxide produced from 54 parts by weight of sublimate by precipitation with sodium hydroxide solution is filtered off, washed out until the filtrate no longer reacts alkaline, suspended in 50 parts by weight of water and 22 parts by weight of o-cresol and the amount of sodium hydroxide solution required to dissolve the latter are added. While stirring vigorously, 20 parts by weight of potassium rhodium are added and the mixture is heated to about 70-900 for a few hours, during which the mercuric oxide is dissolved with the formation of the mercury-containing rhodan compound.
Small residues are then filtered off
EMI1.1
show a strong fungicidal effect.
The constitution belongs to the connection:
EMI1.2
Example 2: 27 parts by weight of sublimate are, as indicated in Example 1, converted into freshly precipitated mercury oxide, 11 parts by weight of o-cresol are added and this is brought into solution with just enough sodium hydroxide solution; then 5 parts by weight of red blood liquor salt are added.
