Three different xenon fluorides, all exergonic and stable, are known: Xenon difluoride, XeF 2; Xenon tetrafluoride, XeF 4; Xenon hexafluoride, XeF 6
Xenon hexafluoride is a noble gas compound with the formula XeF 6. It is one of the three binary fluorides of xenon that have been studied experimentally, the other two being XeF 2 and XeF 4. All known are exergonic and stable at normal temperatures. XeF 6 is the strongest fluorinating agent of the series. It is a colorless solid that readily ...
In this Hunsdiecker-type reaction, xenon difluoride is used to generate the radical intermediate, as well as the fluorine transfer source. [13] XeF 2 can also be used to generate aryl radicals from arylsilanes, and act as an atomic fluorine source to furnish aryl fluorides. [14]
The xenon fluorides behave as both fluoride acceptors and fluoride donors, forming salts that contain such cations as XeF + and Xe 2 F + 3, and anions such as XeF − 5, XeF − 7, and XeF 2− 8. The green, paramagnetic Xe + 2 is formed by the reduction of XeF 2 by xenon gas. [1] XeF 2 also forms coordination complexes with transition metal ...
Xenon difluoride is a powerful fluorinating agent with the chemical formula XeF 2, and one of the most stable xenon compounds. Like most covalent inorganic fluorides it is moisture-sensitive. It decomposes on contact with water vapor, but is otherwise stable in storage. Xenon difluoride is a dense, colourless crystalline solid.
The lighter noble gases xenon and krypton can be made to react with fluorine under special conditions, while argon will undergo chemical transformations only with hydrogen fluoride. [18] Nitrogen, with its very stable triple bonds , requires electric discharge and high temperatures to combine with fluorine directly. [ 19 ]
In chemical thermodynamics, an exergonic reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy). [1] This indicates a spontaneous reaction if the system is closed and initial and final temperatures are the same.
Due to the instability of xenon(II), it is difficult to synthesize organoxenon compounds by using general organic reagents. Organoxenon compounds are frequently prepared from organocadmium species including Cd(Ar F) 2 (where Ar F is a fluorine-containing arene), C 6 F 5 SiF 3, and C 6 F 5 SiMe 3 (used along with fluoride).
