 Verfahren zur Herstellung neuer    Chinone   Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung von    2,5-Bis-äthylenimino-      3,6-bis-acylamino-p-benzochinonen.   Als    Acylamino-      gruppen   kommen insbesondere solche in Frage, deren    Acylreste   die    aliphatischer      Carbonsäuren   mit 2 bis 6    Kohlenstoffatomen,   wie zum Beispiel der Essigsäure,    Propionsäure   oder Buttersäure, sind. Die    Äthyleniminogruppen   können auch an den Kohlenstoffatomen    alkyliert   sein, vorzugsweise durch eine    Methylgruppe.   



  Nach dem erfindungsgemässen Verfahren wird insbesondere das    2,5-Bis-äthylenimino-3,6-bis-acetyl-      amino-p-benzochinon   der Formel 
 EMI1.16 
 hergestellt. Die neuen    Benzochinone   sind gegen Amöben, wie zum Beispiel gegen    Entamoeba      histolytica,   sowie gegen Bakterien wirksam; zudem zeigen sie eine ausgeprägte tumorhemmende Wirkung. 



  Die neuen Verbindungen werden hergestellt, indem man    2,5-Bis-äthylenimino-3,6-dihalogen-p-      benzochinone   mit    N-Metallverbindungen,   insbesondere    Alkalimetall,   wie zum Beispiel    Natriumverbin-      dungen   von    Carbonsäureamiden   zu    2,5-Bis-äthylen-      imino-3,6-bis-acylamino-p-benzochinonen   umsetzt. Unter den    Dihalogenverbindungen   eignen sich besonders die    Dichlor-   und    Dibromverbindungen.   



  Vorzugsweise arbeitet man in indifferenten Lösungsmitteln wie    Dioxan   oder Benzol. Die Reaktion lässt sich bei    Zimmertemperatur   oder bei erhöhter Temperatur durchführen. 



  Die Ausgangsstoffe    sind   bekannt oder können in an sich bekannter Weise hergestellt werden. 



  Die verfahrensgemäss hergestellten    Chinone   können als Bakterizide sowie    als   Heilmittel besonders bei Krebserkrankungen oder durch Amöben verursachten Erkrankungen, zum Beispiel in Form pharmazeutischer Präparate, Verwendung finden. 



  In dem nachfolgenden Beispiel sind die Temperaturen in Celsiusgraden angegeben. 



  Beispiel 25,9 g    3,6-Dichlor-2,5-bis-äthylenimino-p-      benzochinon   werden in 250    cms   absolutem    Dioxan   suspendiert. In die gut gerührte Suspension wird bei einer Temperatur zwischen 10 und 25  16,2 g    Acet-      amid-Natrium   langsam eingetragen. Man rührt 18 Stunden bei Zimmertemperatur, saugt das kristalline Reaktionsprodukt ab und wäscht es gründlich mit Wasser zur Entfernung des gebildeten    Natriumchlo-      rids.   Zum Schluss wird mit Alkohol gewaschen und getrocknet.

   Man    erhält   so das    3,6-Bis-acetamino-2,5-      bis-äthylenimino-p-benzochinon   von dem Zersetzungspunkt 203  und der Formel

 Process for the preparation of new quinones The present invention relates to a process for the preparation of 2,5-bis-ethyleneimino-3,6-bis-acylamino-p-benzoquinones. Particularly suitable acylamino groups are those whose acyl radicals are the aliphatic carboxylic acids with 2 to 6 carbon atoms, such as, for example, acetic acid, propionic acid or butyric acid. The ethyleneimino groups can also be alkylated on the carbon atoms, preferably by a methyl group.



  In the process according to the invention, in particular 2,5-bis-ethylenimino-3,6-bis-acetyl-amino-p-benzoquinone of the formula
 EMI1.16
 manufactured. The new benzoquinones are effective against amoebas, for example against Entamoeba histolytica, as well as against bacteria; they also show a pronounced tumor-inhibiting effect.



  The new compounds are prepared by converting 2,5-bis-ethylenimino-3,6-dihalogen-p-benzoquinones with N-metal compounds, in particular alkali metal, such as sodium compounds of carboxamides to 2,5-bis-ethylene- imino-3,6-bis-acylamino-p-benzoquinones. Among the dihalogen compounds, the dichloro and dibromo compounds are particularly suitable.



  It is preferred to work in inert solvents such as dioxane or benzene. The reaction can be carried out at room temperature or at an elevated temperature.



  The starting materials are known or can be prepared in a manner known per se.



  The quinones produced according to the process can be used as bactericides and as remedies, particularly in the case of cancer or diseases caused by amoeba, for example in the form of pharmaceutical preparations.



  In the example below, the temperatures are given in degrees Celsius.



  Example 25.9 g of 3,6-dichloro-2,5-bis-ethylenimino-p-benzoquinone are suspended in 250 cms of absolute dioxane. At a temperature between 10 and 25, 16.2 g of sodium acetamide are slowly introduced into the well-stirred suspension. The mixture is stirred for 18 hours at room temperature, the crystalline reaction product is filtered off and washed thoroughly with water to remove the sodium chloride formed. Finally, it is washed with alcohol and dried.

   The 3,6-bis-acetamino-2,5-bis-ethylenimino-p-benzoquinone of the decomposition point 203 and the formula is obtained in this way
