    Description / Table of Contents: Preparation of S, S-Diphenyl-N-(trimethylsilyl)sulfimine and Reactions with Tungsten Hexafluoride - X-Ray Structure Analysis of F4W(N=SPh2)Ph2S=NH reacts with Me3SiNMe2 to give S,S-diphenyl-N-(trimethylsilyl)sulfimine (1) in a metathesis. Reaction of WF6 with 1 in a 1:1 molar ratio leads to F5WN=SPh2 (2); a 1:2 molar ratio results in the formation of F4W(N=SPh2)2 (3). The structure of 3 is confirmed by an X-ray analysis.
    Notes: Aus Ph2S=NH wird mit Me3SiNMe2 durch Metathese S,S-Diphenyl-N-(trimethylsilyl)sulfimin (1) erhalten. WF6 reagiert mit 1 im Molverhältnis 1:1 zu F5WN=SPh2 (2) und im Molverhältnis 1:2 zu F4W(N=SPh2)2 (3). Von 3 wird eine Röntgenstrukturanalyse vorgelegt.

    Notes: Heterocycles Containing Tungsten, Phosphorus, Sulphur, and Nitrogen in the Ring SkeletonThe new ligand Me2S(NPPh2NSiMe3)2 (2), prepared from Me2S-(NPPh2)2 (1) and Me3SiN3, reacts with WF6 and WCl6 to form the heterocycles Me2S(NPPh2N)2WF4 (3a) and Me2S(NPPh2N)2WCl4 (3b). The X-ray single-crystal structure analysis exhibits a puckered eight-membered ring with alternating short and long bond lengths. 3a crystallizes with one molecule of dimethylformamide in the space group Cc with a = 1247.3(6), b = 1728.5(9), c = 1543.1(8) pm and β = 102.41(3)°.
