The pyrolysis of some branched perfluoroalkanes has been studied. Homolytic cleavage of the most hindered carbon-carbon bond occurs, followed by coupling and rearrangement of the radicals so formed. This mechanism accounts for all the reaction products. Some kinetic and thermodynamic data are presented.
