A general and efficient protocol was developed for the synthesis of aryl alkyl ethers through metal-free C–OMe bond cleavage under mild reaction conditions. This process displays a wide scope of methoxyarenes and alcohols, including primary, secondary, and tertiary alcohols, as well as natural products, pharmaceuticals, and biologically active alcohols.
