The first compound with a stable xenon-carbon bond: 19F- and 129Xe-n.m.r. spectroscopic evidence for pentafluorophenylxenon(II) fluoroborates

Pentafluorophenylxenon(II) fluoroborates have been synthesized by the reaction of xenon difluoride with tris(pentafluorophenyl)borane and characterized by 129Xe- and 19F-n.m.r. spectroscopy and by reaction with bis(pentafluophenyl)tellurium and pentafluorophenliodine to yield the novel cations [(C6F5)3Te]+ and [(C6F5)2l]+, respectively
