Article abstract of DOI:10.1039/F19817700089

Absolute Arrhenius parameters have been determined for the addition of trifluoromethyl radicals to acetylene, propyne, but-2-yne, 1,1,1-trifluoropropyne and hexafluorobut-2-yne by a competitive method using the previously determined Arrhenius parameters for the addition of trifluoromethyl radicals to ethylene as standard.

. Both the activation energies and the A-factors are larger than those for the addition of trifluoromethyl radicals to similarly substituted olefins.As a result of these opposing effects the rates of addition are similar.
