The First Organoxenon(IV) Compound: Pentafluorophenyldifluoroxenonium(IV) Tetrafluoroborate

Xenon(IV) - carbon bonding has been realized for the first time in the product formed from the reaction of XeF(4) with C(6)F(5)BF(2) in CH(2)Cl(2) at -55 degrees C [Eq. (1)]. [C(6)F(5)XeF(2)][BF(4)] is a strong oxidative fluorinating agent. This xenon(IV) compound fluorinates (C(6)F(5))(3)P to (C(6)F(5))(3)PF(2), C(6)F(5)I to C(6)F(5)IF(2), and I(2) to IF(5). In all cases, [C(6)F(5)Xe][BF(4)] was obtained as a by-product.
