Visible-light–enabled reduction of arylsulfonyl and benzoyl azides to access primary arylsulfonamides and benzoyl amides

Abstract

Photocatalyzed reduction of arylsulfonyl and benzoyl azides, which could serve as temporary masking groups for amides, was achieved to access primary sulfonamides and benzoyl amides in mild conditions using organic reductant. A wide range of structurally diverse arylsulfonamides and benzoyl amides were accessed in good yields using this protocol. The mechanistic pathway of this reaction might generate the key amidyl radical through single-electron transfer (SET).
