An organo-photocatalytic sulfonylimination of alkenes using readily available N-sulfonyl ketimines as bifunctional reagent enables a direct and atom-economic synthesis of valuable β-amino sulfone derivatives as a single regioisomer. A formal insertion of alkenes into cyclic sulfonyl imines affords ring expansion products.
