摘要：

Blue solutions, prepared by dissolving AgF2 in anhydrous hydrogen fluoride (AHF) with BF3or AsF5, oxidize Xe, at ∼20 °C, to produce nearly colorless solids. Overall reactions (all in AHF) are as follows: 2AgF2+ 2BF3+ Xe → XeF2+ 2AgBF4; 4AgF2+ 5AsF5+ 2Xe → Xe2F3AsF6+ 4AgAsF6. Solid AgF2does not interact, at ∼20 °C, with Xe. Ag(I) in AHF is catalytic to the interaction of Xe with F2(Xe + F2→ XeF2), but XeF2precipitates AgF2from Ag(II) AHF solutions (e.g. AgFAsF6+ 2XeF2→ Xe2F3AsF6+ AgF2). To maintain the Ag(I/II) catalyst the fluoride-ion donor, XeF2, must be neutralized with acid, e.g. 2Xe + 2F2+ AsF5→ Xe2F3AsF6. © 1990, American Chemical Society. All rights reserved.
