FxXe(OTeF5)3-x+, O=XeFx(OTeF5)3-x+ (x = 0-2), and O2XeOTeF5+ cations: Their preparation and characterization in solution by 129Xe and 19F NMR spectroscopy

Solvolysis reactions of the parent compounds, Xe(OTeF5)4 and O=Xe(OTeF5)4, in the strong F/OTeF5 acceptor solvent SbF5, led to OTeF5/F ligand redistribution and formation of two series of novel mixed-xenon cations, FxXe(OTeF5)3-x+, O=XeFx(OTeF5)3-x+ (x = 0-2), and O2XeOTeF5+. The previously known XeF3+, XeOF3+, and XeO2F+ cations were observed in addition to the mixed cations. Decomposition of O=XeF2OTeF5+ and O=XeF-(OTeF5)2+ in SbF5 solution led respectively to formation of the previously known XeO2F+ cation and its novel OTeF5 analog O2XeOTeF5+. The O=Xe(OTeF5)3+ cation was not observed in the O=Xe(OTeF5)4/SbF5 systems but was prepared by allowing O=Xe(OTeF5)4 and "Sb(OTeF5)5" to react in SO2ClF. All three series of cations have been characterized in solution by 129Xe and 19F NMR spectroscopy.

Preparation and Properties of TiCl4-n(OTeF5)n (n = 1 - 4), Cs2, and Ti(OTeF5)4 * 2 POCl3

TiCl4 reacts with HOTeF5 to afford TiCl3OTeF5.This compound dismutates via TiCl2(OTeF5)2 and TiCl(OTeF5)3 to Ti(OTeF5)4.With CsOTeF5 the latter forms Cs2 but not Cs.Ti(OTeF5)4 shows strong Lewis acid behavior.Interaction with POCl3, (CH3)2SO, CH3CN, CH3O2OCH3, and CH3NO2 was studied and a correlation of 19F NMR data of the F5TeO group with the donor numbers of the mentioned bases was undertaken.
