Abstract
The ionization potential (IP) of the perfluoro-2-buten-4-yl radical, generated at 950‡C and 1·105 torr by vacuum pyrolysis of perfluorohexene-2, was found to be 10.3 ± 0.1 eV by the electron impact method. This value is close to the IP of the perfluoro radicals n-C3F7 (10.06 ± 0.1 eV) and i-C3F7 (10.5 ± 0.1 eV); however, it is 1.8 eV higher than that of the perfluoroallyl radical, possibly because of the weak delocalization of the unpaired electron. At pyrolysis temperatures above 800‡C, the perfluoro-2-buten-4-yl radical decomposed to the tetrafluoroallene and trifluoromethyl radicals.
