Visible‐Light Photoredox Catalysis: Dehalogenation of Vicinal Dibromo‐, α‐Halo‐, and α,α‐Dibromocarbonyl Compounds.

In the presence of RuCl2(bipy)3, ascorbic acid, 1,5-dimethoxynaphthalene, and visible light the title compounds undergo mild and efficient dehalogenation to afford alkenes, alkynes, monobromides, and ketones.
