S4N3Cl reacts with sulfonic acids and imido- bissulfonyl derivatives under HCl-evolution to the following compounds: S4N3SO3CF3, S4N3N (SO2F)2, S4NSO3CH3HSO3CH3, S4N3N (SO2CF3) SO2Cl and S4N3N (SO2CF3) SO2F, They are yellow solids which decompose when heated below the melting point. The compounds are formed in nearly quantitative yield and have been characterized by elemental analysis, nmr and electronic spectra.
Über Reaktionen von 3-trifluormethylphenylsubstituierten silicium-und zinnorganischen Verbindungen

Several routes were investigated for the preparation of 3-CF3C6H4N[Si(CH3)3]2 2 and 3-CF3C6H4N[Sn(CH3)3]2 3. The latter compound reacts with 3-CF3C6H4NCO to yield [3-CF3C6H4(CH3)3SnN]2CO 4. A substituted urea 5 is also formed from [(CH3)3Si]2NCH3 and 3-CF3C6H4NCO. 5 is used for the preparation of cyclic compounds, with S2Cl2 the ten-membered ring (3-CF3C6H4NCONCH3S2)2 6 is formed. 5 and HN(SO2Cl)2 yield the six-membered ring 3-CF3C6H4NCONCH3(SO2)2NH 7. SeOCl2 and 5 react under formation of a spiro compound (S-CF3C6H4NCONCH3)2Se 8. The compounds were characterized on the basis of mass and 19F NMR spectra.
