Electrochemical Oxidative Alkoxysulfonylation of Alkenes Using Sulfonyl Hydrazines and Alcohols with Hydrogen Evolution

An electrochemical oxidative alkoxysulfonylation of alkenes using sulfonyl hydrazines with alcohols is accomplished, which leads to the easy accessibility of β-alkoxy sulfones, which are not only valuable architectures of many biologically active molecules, but also key building blocks for various organic transformations. Notably, for this efficient electrochemical synthesis protocol, neither metal catalysts nor exogenous additives/oxidants are required. In addition, molecular nitrogen and hydrogen were the sole byproducts in the reaction.
