 Recently , there has been an interest in xenon compounds where xenon is directly bonded to a less electronegative element than fluorine or oxygen , particularly carbon . Electron @-@ withdrawing groups , such as groups with fluorine substitution , are necessary to stabilize these compounds . Numerous such compounds have been characterized , including :
