The reactions of N,N′ -bis(pentafluorophenyl)sulfurdiimide with [(CH3)3Sn]2NCH3, [(CH3)3Sn]3N and [(CH3)3Sn]2NC6F5 yiels the 1:1 adducts 1-3. 1H and 19 F NMR investigations show, that fluorine atoms in the ortho position of the phenyl ring coordinate to the tin atom. This causes an increase of electron density at tin. A similar interpretation is given for the adduct 4 of N,N′-bis(p-chlorophenylsulfonyl)sulfurdiimide and [(CH3)3Sn]2NCH3, where an oxygen atom of the sulfonyl group is bonded to tin.
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.
