This study reports a visible-light-promoted and radical-mediated strategy for the site-specific cleavage of C(sp(3))-C(sp(3)) bonds in ethers. Different cyclic and linear alkyl ethers can be converted into benzoylated acetals and aldehydes or ketones under mild conditions in the presence of Ru(bpy)(3)Cl-2 as a photocatalyst and Zhdankin's lambda(3)-azidoiodane reagent, with moderate to high yields. Control experiments and mechanistic investigations provide a plausible mechanism for this unusual deconstructive esterification of ethers.
