Catalyst‐Free Visible Light‐Induced N−N Bond Cleavage for the Synthesis of Iminophosphorane Using Triarylphosphine and N‐Sulfonyl and N‐Acylaminopyridinium Salt

Year: 2025

Type: article

Abstract: Herein, we explore a visible light‐enabled radical addition for the construction of N‐sulfonyl and N‐acyliminophosphorane using triarylphosphine and N‐sulfonyl and N‐acylaminopyridinium salts in the absence of transition metal, photocatalyst, oxidant or base. This method employs PAr3 as both the reaction catalyst to promote the generation of amidyl radical via N−N bond cleavage of N‐sulfonyl and N‐acylaminopyridinium salts, and materials for the preparation of N‐sulfonyl and N‐acyliminophosphorane products. This transformation exhibits abroad substrate scope and good functional group compatibility.
