Main-group derivatives of the highly electronegative OIF4O-group

The oxygen-bonded derivatives FXeOIOF4 and Xe(OIOF4)2, including all isomers derived from cis-trans isomerism associated with the OIF4O-group, have been observed as the reaction products in IO2F3/XeF2 solution mixtures by 19F and 129Xe NMR spectroscopy. The 129Xe chemical shifts have been used to establish that the OIF4O-group is the most electronegative group known next to fluorine. In addition, the Xe(IV) derivative F3XeOIOF4, has also been …
