Abstract
We report the photocatalytic functionalization of terminal alkenes to vicinal dichlorides using visible light and FeCl3 as catalyst, LiCl as chloride source, and air as oxidant. The transformation is proposed to be initiated by ligand-to-metal charge transfer (LMCT) bond homolysis of a Fe-Cl bond giving a highly reactive chloride radical, able to initiate the functionalization of olefins.

Abstract
We report the photocatalytic functionalization of terminal alkenes to vicinal dichlorides using visible light and FeCl3 as catalyst, LiCl as chloride source, and air as oxidant. The transformation is proposed to be initiated by ligand-to-metal charge transfer (LMCT) bond homolysis of a Fe-Cl bond giving a highly reactive chloride radical, able to initiate the functionalization of olefins. The process shows high chemo-selectivity and functional group tolerance with a yield of up to 94% under mild conditions.
