Selective Electrochemical Benzylic C(sp3)−H Oxidations in Fluoroalcohols

A site‐selective electrochemical benzylic C(sp3)−H oxidation reaction of aryl alkanes has been reported for synthesis of the desired products. This method significantly expands the scope and enhances the selectivity of aryl aldehydes and fluorinated ethers. Electricity is used as a sustainable oxidant and promote H2 evolution. This protocol is eco‐friendly and easy to handle as it uses a simple undivided cell in mild conditions without employing any catalyst and oxidant. An efficient electrochemical benzylic C(sp3)−H oxidation reaction of aryl alkanes has been developed to selectively generate significant aryl aldehydes and fluorinated ethers products using electric current as the oxidant, eliminating the requirement for catalysts or additional oxidizing agents.
