Description

Zierfahren zur Herstellung von Derivaten des Athylenimins Es wurde gefunden, daß man wertvolle Derivate des Äthylenimins erhält, wenn man Aminsulfenhalogenide der allgemeinen Formel in der R einen Cycloalkylenrest, dessen Kohlenstoffkette durch Sauerstoff oder Schwefel unterbrochen sein kann, und X ein Halogenatom bedeutet, in Gegenwart säurebindender Mittel mit Äthylenimin zu Verbindungen der allgemeinen Formel umsetzt. Die Herstellung der als Ausgangsmaterial dienenden Aminsulfenhalogenide bildet den Gegenstand eines älteren Vorschlages.Zierfahren for the preparation of derivatives of ethylene imine It has been found that valuable derivatives of ethylene imine are obtained if amine sulfen halides of the general formula in which R is a cycloalkylene radical, the carbon chain of which can be interrupted by oxygen or sulfur, and X is a halogen atom, in the presence of acid-binding agents with ethyleneimine to form compounds of the general formula implements. The preparation of the amine sulfen halides used as starting material forms the subject of an earlier proposal.

Die Umsetzung der Aminsulfenhalogenide mit Äthylenimin wird zweckmäßig in einem inerten Verdünnungsmittel bei Temperaturen zwischen o und 5° vorgenommen. Bei der Reaktion muß ein säurebindendes Mittel anwesend sein, wozu sich vor allem tertiäre Amine, wie Triäthylamin und Pyridin, eignen.The reaction of the aminesulfenhalides with ethyleneimine is expedient in an inert diluent at temperatures between 0 and 5 ° performed. During the reaction, an acid-binding agent must be present, which is especially useful tertiary amines such as triethylamine and pyridine are suitable.

Es ist überraschend, daß die erfindungsgemäß hergestellten Verbindungen, die eine N-S-N--Bindung enthalten, beständiger sind als beispielsweise das bekannte Methansulfonsäureäthylenimid und andere bekannte Produkte, die eine enthalten. Während eine Reindarstellung der bekannten Produkte wegen der starken Polymeri= sationsneigung derselben nicht immer möglich ist, sind die erfindungsgemäß hergestellten Äthyleniminderivate unter normalen Bedingungen beständig. Sie sind daher gut isolierbar und lagerfähig.It is surprising that the compounds prepared according to the invention which contain an NSN bond are more stable than, for example, the known methanesulfonic acid ethyleneimide and other known products which contain a contain. While the known products cannot always be prepared in pure form because of their strong tendency to polymerize, the ethyleneimine derivatives prepared according to the invention are stable under normal conditions. They are therefore easy to isolate and can be stored.

Die neuen Äthyleniminderivate sind wertvolle Heilmittel. Infolge ihrer leichten Löslichkeit können sie sowohl in Lösung zur Injektion als auch oral verabreicht werden. Beispiel i 138 g (o,go Mol) frisch hergestelltes, nicht destilliertes Morpholinosulfenchlorid, in 20o ccm Tetrachlorkoblenstoff gelöst, werden unter kräftigem Rühren und Feuchtigkeitsausschluß bei o bis 5° Innentemperatur zu einer Lösung von 94,5 g (o,93 Mol) Triäthylamin und 38,75 g (o,go Mol) Äthylenimin in 40o ccm Tetrachlorkohlenstoff langsam zugetropft. Die Re-. aktion - verläuft exotherm unter starker Salzabscheidung: Nach Beendigung des Zutropfens wird die Außenkühlung (Kältemischung) entfernt, so daß der Kolbeninhalt allmählich Raumtemperatur erreicht, und noch 3 Stunden nachgerührt. Vom abgeschiedenen Triäthylaminhydrochlorid wird abgesaugt, das Filtrat mit Kohle versetzt und nach dem Filtrieren unter Wasserstrahlvakuum das Lösungsmittel zunächst bei 3o bis 4o° Badtemperatur, zuletzt bei 5o° entfernt. Der Kolbenrückstand wird der Hochvakuumdestillation unterworfen und liefert 8o g Morpholino-N-äthylenirnino-monosulfid, eine leicht gelbgrün gefärbte Flüssigkeit vom Kp. 0,4 63 bis 65°. Die Ausbeute beträgt 55 0/0 der Theorie, bezogen auf eingesetztes Äthylenimif. Analyse für C,H1zON,S: Berechnet: N 17,49 0/0. 0 '9,99 0/". S --0,010/,; gefunden: .N 17,200/0, 0 10,340/0 .S 19,8o0/0.The new ethyleneimine derivatives are valuable medicinal products. Because of their ready solubility, they can be administered both in solution for injection and orally. Example i 138 g (0.2 moles) of freshly prepared, undistilled morpholinosulfen chloride, dissolved in 20 cc of carbon tetrachloride, are stirred vigorously and with exclusion of moisture at an internal temperature of 0 to 5 ° to form a solution of 94.5 g (0.93 moles) of triethylamine and 38.75 g (0.2 moles) of ethyleneimine in 40o ccm of carbon tetrachloride were slowly added dropwise. The re-. action - takes place exothermically with strong salt deposition: After the dropping has ended, the external cooling (cold mixture) is removed so that the contents of the flask gradually reach room temperature and the mixture is stirred for another 3 hours. The precipitated triethylamine hydrochloride is filtered off with suction, the filtrate is treated with charcoal and, after filtering under a water jet vacuum, the solvent is removed initially at a bath temperature of 3o to 40 ° and finally at 50 °. The residue on the flask is subjected to high vacuum distillation and yields 80 g of morpholino-N-ethyleneinino-monosulfide, a light yellow-green colored liquid with a boiling point of 0.4 63 to 65 °. The yield is 55% of theory, based on the ethylene imide used. Analysis for C, H2 ZON, S: Calculated: N 17.49 0/0. 0 '9.99 0 / ". S -0.010 /,; found: .N 17.200 / 0, 0 10.340 / 0 .S 19.8o0 / 0.

Das Produkt ist in allen gebräuchlichen Lösungsmitteln, wie .Alkoholen, aromatischen Kohlenwasserstoffen, sowie in Äther, Aceton, Essigester, PetroI-äther, Wasser und in Öl löslich und.von_guter Haltbarkeit.The product is in all common solvents, such as alcohols, aromatic hydrocarbons, as well as in ether, acetone, ethyl acetate, petroleum ether, Soluble in water and in oil and has a good shelf life.
