Shape of cf3 radical
Webb3 maj 2004 · The shape of the onset of the ionization efficiency curve shows that the adiabatic ionization potential of the radical is much lower than the vertical one, and hence that the equilibrium configuration of the CF 3+ ion is very different from that of the molecule. Autoionization probably accounts for some of the ionization near threshold. WebbThese nucleophilic, electrophilic, and radical CF3 transfer reagents were tested under different experimental conditions, such as standalone reagents for direct trifluoromethylation reactions...
