    Description / Table of Contents: Reactions of Transition Metal Halides with Derivatives of Dimethylsulfoximine - X-Ray Single Structure Analysis of F5WNS(O)Me2 und F4[NS(O)Me2]2WF6 reacts with Me2S(O)NSiMe3 (1) in a molar ratio 1:1 to give F5WNS(O)Me2 (2), which reacts further with 1 to yield F4W[NS(O)Me2]2 (3). 2 and 3 were characterized i. a. by X-ray crystal structure analyses. In these compounds there is evidence of multiple bonding between N and W. Reaction of 3 with Me2S(O)NLi leads to substitution of a further fluorine atom with formation of F3W[NS(O)Me2]3 (4). Cl4W[NS(O)Me2]2 (5) and Cl4MoNS(O)Me2 · CH3CN (6) are formed by the reaction of WCl6 and MoCl5 with 1.
    Notes: WF6 reagiert mit Me2S(O)NSiMe3 (1) im Molverhältnis 1:1 zu F5WNS(O)Me2, das mit 1 zu F4W[NS(O)Me2]2 (3) umgesetzt wird 2 und 3 werden u. a. durch Röntgenstrukturanalysen charakterisiert. In diesen Verbindungen besteht ein Mehrfachbindungsteil zwischen N und W. Mit Me2S(O)NLi reagiert 3 unter Substitution eines weiteren Fluoratoms zu F3W[NS(O)Me2]3 (4). Cl4W[NS(O)Me2]2 (5) und Cl4MoNS(O)Me2 · CH3CN (6) entstehen bei der Umsetzung von WCl6 und MoCl5 mit 1.
