Description
In dem Hauptpatent ist die fungistatisch und bakteriostatiseh wirksame Acelylemerbindung 1-lsopropenyl-2-benzovlacetvlen beschrieben.In the main patent it is fungistatic and bacteriostatic acetyl binding 1-isopropenyl-2-benzovlacetylene described.
In dem Hauptpatent ist ferner ein Verfahren zur Herstellung dieser Verbindung beschrieben. Das Verfahren ist dadurch gekenn/eichnet. daß man die aus der 2-Isopropyl-aeetylen-Verbindung hergestellte Ciirgnardverbindung mit Benzaldehyd umsetzt und das Umsetzungsprodukl dann zu dem entsprechenden Keton oxydiert.The main patent also describes a process for producing this compound. The procedure is thereby identified / calibrated. that one prepared from the 2-isopropyl-aeetylene compound Ciirgnardverbindungen reacts with benzaldehyde and the implementation product then to the corresponding one Ketone oxidizes.
Bei der weiteren . lisbildung dieser Erfindung wurde gefunden, daß diese Verbindung ausgezeichnete fungi-Statische und baktcriostatisehe Eigenschaften hat. «venη der Phenyln-st in p-Stellung chloriert ist.At the other. In the formation of this invention, this compound was found to be excellent fungi-static and has bacteriostatic properties. «Venη the phenyln-st is chlorinated in the p-position.
Die neue Verbindung kann analog zu dem im Hauptfialcnt beschriebenen Verfahren hergestellt werden. Man setzt die aus dem 2-Isopropenvl-aeetvlen hergestellte Grignardvcrbindung mit p-Chlorben/aldehyd »im und oxydiert das Umsetzungsprodukt zu dem entsprechenden Keton.The new connection can be analogous to that in the main event described method are produced. One sets the one made from the 2-isopropene-aeetvlen Grignard compound with p-chlorobenzene / aldehyde and oxidizes the reaction product to the corresponding ketone.
