文摘

Transition-metal-free dehalogenation of various aryl halides (iodides and bromides) can take place efficiently at 70–110 °C in the presence of a catalytic amount of 1, 10-phenanthroline and t-BuOK using THF or Dioxane as solvent. Control experiments indicated that radical transfer occurred between aryl radical and alkyl CH bond to generate alkyl radical.
