Synthesis, NMR spectroscopic characterisation and reactions of 2,6-difluorophenylxenon fluoride, 2,6-F2C6H3XeF

[2,6-F2C6H3Xe][BF4] is quantitatively transferred into 2,6-F2C6H3XeF in reactions with [NMe4]F. The latter has been isolated as a colourless solid which is stable in dichloromethane solution at room temperature for approximately 1 h. 2,6-F2C6H3XeF readily reacts with Me3SiX (X = Cl, Br, CN, NCO, OCOCF3, OSO2CF3, C6F5, 2,6-F2C6H3) to give compounds of general compositions 2,6-F2C6H3XeX which were identified by multinuclear NMR experiments. Evidence was found for C6H5Xe(2,6-F2C6H3) as a product of the reaction with C6H5SiF3.
