A mild, simple, and controllable metal-free photocatalytic system for the transformation of arylmethyl bromides to corresponding alcohols and aldehydes in high yields with visible-light irradiation has been achieved. Eosin Y was found to be an efficient promoter for this oxidative dehalogenation reaction under photo irradiation conditions.

Abstract α-Tosyloxy ketones and α-mesyloxy ketones were directly prepared from alcohols in one pot by treatment with hypervalentiodine(V) reagents in combination with p-toluenesulfonic acid and methanesulfonic acid, respectively, in moderate to good yields. Reactions were also feasible under solvent-free conditions.
