Sulfonyl radical mediated processes have been considered as a powerful strategy for the construction of sulfonyl compounds. However, an efficient and high atom-economical radical approach to the synthesis of sulfonate esters is still rare, owing to the limited tactics to achieve alkoxysulfonyl radicals. Herein, an electrochemical anodic oxidation of inorganic sulfites with alcohols is developed to

alkylation of allylic alcohols by alkyl nitriles with concomitant 1,2‐arylmigration was developed. Formation of the alkyl nitrile radical was followed by its intermolecular addition to alkenes and the migration of a vicinal aryl group with the concomitant generation of a carbonyl functionality to complete the domino sequence. Mechanistic studies suggested that 1,2‐arylmigration proceeded through a
