ABSTRACT We have disclosed the 9‐fluorenol‐catalyzed reductive dehalogenation of aryl halides. 9‐Fluorenol, a readily available and structurally simple organic compound, serves as a catalytic single‐electron reductant under light‐ and electricity‐free conditions. Another key feature of this transformation is isopropyl alcohol, which simultaneously functions as the solvent, terminal reductant, and hydrogen source. Consequently, the reaction system requires only four components: substrate, catalyst, base, and solvent. This operationally simple method enabled efficient hydrodehalogenation of a wide range of aryl iodides as well as electron‐deficient aryl bromides and chlorides.
