The reports of photoredox cleavage of C-H bond adjacent to the oxygen atom of benzyl ethers were scarce.1,2 Herein we report a visible-light-promoted cleavage of the O-a-sp3 C–H bond of alkyl benzyl ethers.The alkyl benzyl ethers were converted to the alkyl esters or alkyl alcohols in good to excellent yields under irradiation of visible light.The reaction is proposed to go through oxonium ion pathway.
