    Notes: Abstract The novel peroxides H2NSO2OOCH2 R (1 a:R=CH2CH3;1 b:R=CH2CH2CH3) are obtained by reaction of sulphamoyl chloride with the appropriate hydroperoxides in the presence of pyridine (temperature below −30 °C, solvent diethyl ether). The solvent-free liquids1 deflagrate at ca. 0 °C. Hydrolysis or ammonolysis of1 generates the hydroperoxide and sulphamic acid or sulphamide, respectively. Controlled thermolysis of1 affords sulphamic acid and carbonyl compounds, i.e. propanal andn-propyl propanoate from1 a, butanal, 2-methylpropanal andn-butyln-butyrate from1 b. These products suggest a nonradical cyclic decomposition path-way.

    Notes: Abstract The alkyl-chlorosilyl-peroxides1 and2, the alkoxysilylalkyl-peroxides3 to7 (Table 1) as well as the hitherto unknown chlorosilanes (n-PrO)Me 2SiCl and (t-BuO)Me 2SiCl were prepared, isolated and characterized by analytical and1H-NMR data. Attempts to isolate the unstable peroxides (i-PrO)3SiOOCMe 3 and (Me 3CO)Me 2SiOOCMe 2 Ph failed.

    Description / Table of Contents: Investigations on Bis(methylsulfonyl)-amine (Dimesylamine). IV. Synthesis of N-Alkyl-dimesylamines with Tetra-n-butylammonium DimesylaminidePrimary and secondary alkyl iodides, diiodomethane, and α,ω-diiodoalkanes I[CH2]nI with n 〉 2 react with [(C4H9)4N]N(SO2Me)2 in boiling CHCl3 to form the corresponding dimesylamino alkanes. By this procedure, the new compounds 3 - 9, 11, 13 and 14 were prepared. Addition of bromine to the allyl compound 9 affords 10. Alkyl chlorides and bromides do not react under these conditions. Cyclohexyl and tert.-butyl iodide eliminate olefins. ICH2CH2I is decomposed, forming I2. 1,2-Bis(dimesylamino)-ethane (12), however, is prepared from ICH2CH2I and (MeSO2)2NCl. The kinetics of the alkaline hydrolysis of MeN(SO2Me)2 (1) is investigated.
    Notes: Primäre und sekundäre Iodalkane, Diiodmethan und α,ω-Diiodalkane I[CH2]nI mit n 〉 2 setzen sich mit [(C4H9)4N]N(SO2Me)2 in siedendem Chloroform zu den entsprechenden Dimesylaminoalkanen um. Auf diese Weise wurden die neuen Verbindungen 3 - 9, 11, 13 und 14 erhalten. Die Allylverbindung 9 addiert Brom unter Bildung von 10. Chlor- und Bromalkane werden unter den gleichen Bedingungen nicht angegriffen. Cyclohexyl- und tert.-Butyliodid zersetzen sich unter Olefin-Eliminierung, 1,2-Diiodethan unter I2-Abscheidung. 1,2-Bis(dimesylamino)-ethan (12) erhält man jedoch aus ICH2CH2I und (MeSO2)2NCl. Die Kinetik der Basenhydrolyse von MeN(SO2Me)2 (1) wurde untersucht.

    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.
