    Description / Table of Contents: A New Synthetic Route for the Preparation of Perfluoroorganoselenium and -tellurium CompoundsA new synthetic route for the preparation of perfluoroorganoselenium and -tellurium compounds is presented. By the reaction of disodiumchalcogenides Na2Ex (x = 1, 2; E = Se, Te) with C6F5X or C2F5X (X = Br, I) in liquid ammonia, thf or dmf the corresponding selenium and tellurium compounds are obtained in good yields. The reaction conditions are described.
    Notes: Perfluororganoselen- und -tellur-Verbindungen entstehen bei den Reaktionen von Dinatriumchalkogeniden Na2Ex (x = 1, 2; E = Se, Te) mit C6F5X oder C2F5X (X = Br, I) in flüssigem Ammoniak, THF oder DMF in guten Ausbeuten. Die Reaktionsbedingungen werden beschrieben.

    Description / Table of Contents: Lewis-Acid Initiated Syntheses of Xenon-Oxo Compounds - a 129Xe-NMR StudyThe reaction of XeF2 with B(OR)3 yield FXeOR (R: SO2CF3) and Xe(OR)2 (R: COCF3), respectively. In the second case the intermediate formation of FXeOCOCF3 is detectable. In a solution of XeF2 and BF3 · O(CH3)2 in CD3CN the cation [FXe.NCCD3]+ can be observed. The syntheses of FXeOR (R: SO2CF3, SO2C4F9) and Xe(OR)2 (R:COCF3, COC2F5) also succeed in the reaction of XeF2 with the corresponding alkali metal sulfonates and carboxylates in the presence of BF3 · O(CH3)2. Due to the 129Xe-NMR spectra the mechanism of formation and the bond types of these partly new derivatives are discussed.
    Notes: Bei den Reaktionen von XeF2 mit B(OR)3 entstehen FXeOR (R: SO2CF3) bzw. Xe(OR)2 (R:COCF3); dabei ist auch die intermediäre Bildung von FXeOCOCF3 nachweisbar. In einer Lösung von Xef2 und BF3 · O(CH3)2 in CD3CN wird das Vorliegen von [FXe · NCCD3]+ beobachtet. Die Synthesen von FXeOR (R: SO2CF3, SO2C4F9) sowie Xe(OR)2 (R:COCF3,COC2F5) gelingen ebenfalls durch die Umsetzungen von XeF2 mit den entsprechenden Alkalimetallsulfonaten bzw. -carboxylaten in Gegenwart von BF3 · O(CH3)2. Anhand der129Xe-NMR Spektren werden die Bildungsmechanismen und die Bindungsverhältnisse dieser teilweise neuen Xenonderivate diskutiert.
