    Description / Table of Contents: Investigations on Bis(methylsulfonyl)-amine (Dimesylamine). III. Onium Salts of DimesylamineThirty-five salts of the strong acid HN(SO2Me)2 containing onium cations are reported. These include higher quaternary ammonium salts which show excellent solubility in solvents of low polarity, thus being particularly useful for preparing solutions of “naked” (MeSO2)2N- or corresponding ion-pairs. Pyrolysis of the quaternary ammonium salts at temperatures of 200 - 250°C produces tertiary amines and N-alkyl-dimesylamines by (N → N′)-alkyl transfer. Alkene formation is not observed.
    Notes: Es werden 35 Onium-Salze der starken Säure HN(SO2Me)2 beschrieben. Besonders die höheren Tetraalkylammoniumsalze eignen sich wegen ihrer ausgezeichneten Löslichkeit in polar-aprotischen oder apolaren Medien zur Herstellung von Lösungen des „nackten“ Anions (MeSO2)2N- oder entsprechender Ionenpaare. Bei der trockenen Thermolyse der quartären Ammoniumsalze bei 200 - 250°C tritt keine Alken-Eliminierung ein, sondern ausschließlich (N → N′)-Umalkylierung unter Bildung von tertiärem Amin und N-Alkyldimesylamin.
