Description
Summary:Reactions of Hg(OTeF5)2 with excess amounts of NSF[sub 3] at 0 [degree]C result in the formation of NSF[sub 3] adducts having the compositions. When the reactions are carried out at room temperature, oxygen/fluorine metatheses occur yielding the F2OSNderivatives. The proposed reaction pathway leading to F2OSNgroup formation occurs by nucleophilic attack by a F[sub 5]TeO-group at the sulfur(VI) atom of NSF3, followed by TeF6 elimination. Tellurium hexafluoride formation was confirmed by 19F NMR spectroscopy. The NSF[sub 3] molecules are terminally N-coordinated to mercury, whereas the F2OSNligands are N-bridged to two mercury atoms. The compound series was characterized by low-temperature single-crystal X-ray diffraction and low-temperature Raman spectroscopy. Compounds 4 and 5 also provide the only examples of F2OSN derivatives of mercury that have been characterized by single-crystal X-ray diffraction.
