Abstract
The thermal decomposition of some highly branched perfluoroalkanes in the presence of molecular halogens (Cl2, Br2, I2) has been studied. Th e clear-cut cleavage of the most hindered carbon-carbon bond and the t rapping by halogens of the intermediate radicals so formed account for the product distribution. Kinetic measurements support a mechanism ba sed on homolytic rupture of the perfluoroalkanes as the rate-determini ng step, followed by the fast reaction of the intermediates with halog ens.
