Abstract
Phenanthroline and tert-butoxide are powerful radical initiators, that enable a catalyzed transition-metal-free allylic isomerization of allylic alcoholsvia a base-promoted allylic anion pathway. The radical pathway is supported by experimental evidence that includes kinetic study, kinetic isotope effect, isotope-labeling experiments, trapping experiments, and EPR experiments.
