Abstract

The radiolytically generated radical anion of decafluorobenzophenone normally leads to the formation of ketyl radical by protonation. However, in the presence of triethylamine, the ketyl radical formation can be prevented by a contact ion-pair formation. The absorption spectra for such an ion-pair is located at a shorter wavelength than the corresponding solvated radical anion and exhibits solvent-dependent spectral shift characteristic of the radical anion of decafluorobenzophenone.
