Application of the Marcus Cross Relation to Hydrogen Atom Transfer Reactions
Justine P. Roth,*

Tae-Jin Won,
James M. Mayer
The transfer of a hydrogen atom--a proton and an electron--is a
fundamental process in chemistry and biology. A variety of hydrogen atom transfer reactions, involving iron complexes, phenols,
hydroxylamines, tBuOOH, toluene, and related radicals, are
shown to follow the Marcus cross relation. Thus, the Marcus theory
formalism based on ground-state energetics and self-exchange rates,
originally developed for electron transfer processes, is also valuable
for hydrogen atom transfer. Compounds that undergo slow proton transfer (C-H bonds) or slow electron transfer (cobalt complexes) also undergo
slow hydrogen atom transfer. Limitations of this approach are also
discussed.
