Abstract
A metal-free photo-mediated activation of aliphatic alcohols provides differently functionalized benzimidazoles under mild conditions. The interplay of a photocatalyst and a HAT reagent facilitated the activation of aliphatic alcohols. A wide array of diamines with different functional groups were well tolerated.
