Synthesis and characterization of TeF5OF

A new method for the synthesis of hypofluorites was discovered utilizing fluorine fluorosulfate as the fluorinating agent. The method was successfully applied to the high-yield synthesis of the new hypofluorite TeF5OF. The compound was also prepared in lower yield by the fluorination of TeF5OH with a concentrated NF4HF2 solution. The physical properties and infrared, Raman, 19F NMR and mass spectra of TeF5OF are reported. The vibrational spectra of TeF5OCl were redetermined, and complete vibrational assignments are given for TeF5OF and TeF5OCl.
