The relative rates of hydrogen atom abstraction from a series of
13 homoaryl and heteroarylmethanes by t-butoxy radical were determined at 70°C. The attacking radical was photochemically generated
from di-t-butyl peroxide. A relatively small range of relative rates
(factor of seven) has been found among the compounds studied. The
relative...
The relative rates of hydrogen atom abstraction from a series of 13 homoaryl
and heteroarylmethanes by the nucleophilic undecyl radical, thermally generated
from lauroyl peroxide, were determined at 70 °C. A reactivity range of 15 was
obtained. Substantial differences in reactivity among isomers were found. The
relative reactivities of the...
