EXPERIMENTAL AND THEORETICAL-STUDIES ON THE REACTIVITIES OF PARTIALLYAND FULLY FLUORINATED PRIMARY ALKYL RADICALS

Absolute rate constants for hydrogen abstraction from n-Bu3SnH by a nu mber of partially-fluorinated and fully fluorinated n-alkyl radicals h ave been measured. The C-H and C-C bond dissociation energies for a nu mber of pertinent hydrofluorocarbons have been calculated by DFT. The rate data are compared with those for addition of the same radicals to styrene, and the reactivities of these radicals are discussed in term s of their electronegativies, their structure and the thermodynamics o f their reactions.
