    Description / Table of Contents: Demonstration of the Existence of 2-Silapropane-2, 2-dithiolatesThe unstable title compounds M2[S2Si(CH3)2] with M = Li, Na, K have been prepared by reaction of Cl2Si(CH3)2 with the corresponding sulfide in tetrahydrofurane. The existence of the dithiolates has been demonstrated by means of spectroscopic and chemical methods. They react with alkyl halides forming 2, 2-bis(alkylthio)-2-silapropanes. With carbon disulfide no reaction occurs.The reaction between Cl2Si(CH3)2 and H2S in the presence of pyridine produces at -78°C also unstable 2-silapropane-2, 2-dithiol (HS)2Si(CH3)2.
    Notes: Die instabilen Titelverbindungen M2[S2Si(CH3)2] mit M = Li, Na, K wurden durch Umsetzung von Cl2Si(CH3)2 mit dem entsprechenden Sulfid in Tetrahydrofuran hergestellt. Die Existenz der Dithiolate wurde mit Hilfe spektroskopischer und chemischer Methoden bewiesen. Sie reagieren mit Alkylhalogeniden zu 2, 2-Bis(alkylthio)-2-silapropanen. Mit Kohlenstoffdisulfid findet keine Umsetzung statt.Die Reaktion zwischen Cl2Si(CH3)2 und H2S in Gegenwart von Pyridin führt bei -78°C zu ebenfalls instabilem 2-Silapropan-2, 2-dithiol (HS)2Si(CH3)2.
