General description

Xenon fluoride may be obtained by interacting elemental xenon and fluorine in the temperature range of 473-523 oC and 5 absolute atmosphere. Xenon difluoride readily interacts with Lewis acid and forms complexes.

Application

Very useful fluorination agent. Xenon fluoride may be used as a fluorinating agent to analyze sulphur, selenium and tellurium by gas chromatography.

Packaging

Packaged in PFA/FEP bottles

Palladium(II) aryliodo complexes bearing chelating diphosphine ligands react with XeF2, giving iodoarene and rare palladium(II) difluoro complexes. The reaction is general with regard to the aryl group, with even C6F5-I undergoing facile reductive elimination from a Pd center.

The existence of the trifluoroxenate(II) anion, XeF(3)(-), had been postulated in a prior NMR study of the exchange between fluoride ion and XeF(2) in CH(3)CN solution. The enthalpy of activation for this exchange, ΔH(⧧), has now been determined by use
