Description

Description générale

Hexafluorobenzene was repoted to be a sensitive ¹⁹F NMR indicator of tumor oxygenation. Rotational Raman spectra of hexafluorobenzenehas been studied under high resolution using a single mode argon laser as the exciting source. Hexafluorobenzene in the gas phase reacts spontaneously with lithium amalgam, to give a solid and intimate mixture of lithium fluoride and elemental polymeric carbon with a small amount of superstoichiometric lithium. Hexafluorobenzene forms series of 1:1 complexes with naphthalene, anthracene,phenanthrene, pyrene and triphenylene.

Application

Hexafluorobenzene can be used as a standard in ¹⁹Fluorine NMR (nuclear magnetic resonance) spectroscopy and also as a solvent in ¹³Carbon and ¹H NMR spectroscopy.
