CF3SO2N=SCl2 reagiert mit (CH3)2S[NSi(CH3)3]2, (C4H8)S[NSi(CH3)3]2 oder (C5H10)S[NSi(CH3)3]2 unter Trimethylchlorsilanabspaltung zu den achtgliedrigen S4N4-Derivaten S4N4(NSO2CF3)2(CH3)4 3, S4N4(NSO2CF3)2(C4H8)2 4a und S4N4(NSO2CF3)2(C5H1 0)2 4b. In den achtgliedrigen SN-Ringen haben die Schwefelatome die Koordinationszahl 3 und 4. Die Röntgenstrukturanalyse von 4a ergab eine Sessel-Konformation. 4a kristallisiert orthorhombisch in der Raumgruppe Pna21 mit a = 17,641(4), b = 6,406(2), c = 19,130(4) Å, dx = 1,815 g cm-3 und Z = 4. Die mittleren S—N-Abstände betragen an den vierfach koordinierten Schwefelatomen 1,597 Å und an den Schwefelatomen mit der Koordinationszahl 3 1,650 Å.CF3SO2N—SCl2 reagiert mit trimethylzinnhaltigen S—N-Verbindungen zum bekannten CF3SO2N[Sn(CH3)3]S(CH3)NSO2CF3 und Dimethylzinndichlorid.Synthesis and X-Ray Structure Analysis of S4N4-Derivatives with Threefold and Fourfold Coordinated Sulfur AtomsCF3SO2N=SCl2 reacts with (CH3)2S[NSi(CH3)3]2, (C4H8)S[NSi(CH3)3]2 or (C5H10S[NSi(CH3)2]2 under elimination of (CH3)3SiCl to yield the eight-membered S4N4 derivatives S4N4-NSO2CF3)2(CH3)4, 3, S4N4(NSO2CF3)2(C4H8)2 4a und S4N4(NSO2CF3)2(C5H1 0)2 4b. In the eight-membered SN-rings the sulfur atoms have the coordination number 3 and 4. The X-ray structure analysis of 4a revealed a chair conformation. 4a crystallizes in the orthorhombic space group Pna21 with a = 17.641(4), b = 6.406(2), c = 19.130(4) Å, dx = 1.815 g cm-3, and Z = 4. The average S—N distance was found to be 1.597 Å at fourfold coordinated sulfur atoms and 1.650 Å at sulfur with coordination number 3. CF3SO2N=SCl2 reacts with trimethyl tin-containing S—N compounds to the known CF3SO2N[Sn(CH3)3]S(CH3)NSO2CF3 and dimethyl tin dichloride.
