    Description / Table of Contents: Synthesis and Structures of Bicyclic Phosphoranes  -  Products Resulting from the Reaction of Hexafluoroacetone with Mercury SaltsHg(SCN)2 reacts with hexafluoroacetone (HFA) to give the cycloaddition product 1. Reaction of 1 with CF3SCl, ClSC2F4SCl, and Br2 leads to elimination of mercury with formation of the disulfanes 2,3, and 4, respectively. 1 reacts with Ph2PCl to yield the bicyclic phosphorane 5. The reaction of Hg(CN)2 with HFA and Ph2PCl leads to 7. The bicyclic fragment present in 7 is also found in 8, which is formed from PhP(CN)2 and HFA. The X-ray structure analysis of 5, 7, and 8 are reported.
    Notes: Aus Hg(SCN)2 wird mit Hexafluoraceton (HFA) das Cycloadditionsprodukt 1 erhalten. Dieses reagiert mit CF3SCl, ClSC2F4SCl und Br2 unter Eliminierung des Quecksilbers zu den Disulfanen 2,3 und 4. Aus 1 und Ph2PCl entsteht das bicyclische Phosphoran 5. Hg(CN)2, HFA und Ph2PCl reagieren zu 7. Die gleichen bicyclischen Strukturelemente, wie sie in 7 vorliegen, werden auch in 8, dem Reaktionsprodukt aus PhP(CN)2 und HFA, gefunden. Die Röntgenstrukturanalysen von 5, 7 und 8 werden mitgeteilt.
