A thiazolium precatalyst facilitates electrochemical oxidation of thiolate anions, leading to deleterious formation of disulfide byproducts. For the reaction of a broad range of aldehyde and thiol substrates, thioesters were obtained in very good yields . This approach provides an atom-efficient thioesterification that circumvents the need for stoichiometric exogenous oxidants, high cell potentials, or redox mediators.
