Abstract
The abstraction of hydrogen atoms from eight olefins by deutero‐methyl radicals formed in the photolysis of deutero‐acetone has been investigated over a temperature range from 180°C to 340°C. The activation energies of those reactions have been determined relative to the activation energy of the combination of methyl radicals. The activation energies are 10.0 kcal for ethylene and 7.5±0.3 kcal for the other seven olefins. The collision theory ``P'' factors are all of the order of 10−3 or less.Keywords
