Demonstrates efficient C-C bond cleavage and C-N bond formation in spiro-dihydroquinazolinones, suggesting broad substrate compatibility.
A visible‐light‐photoredox‐catalyzed deconstructive azotization of spiro‐dihydroquinazolinones with aryldiazonium salts is reported, enabling efficient CC bond cleavage and CN bond formation, furnishing a wide range of structurally diverse unsymmetrical arylalkyl azo compounds under mild conditions. This transformation exhibits broad substrate compatibility, accommodating a diverse range of spiro‐dihydroquinazolinones and aryldiazonium salts with different substituents. Moreover, control experiments confirm that the reaction proceeds through a radical‐mediated mechanism.
