Abstract:
Application of aryltriazenes as safe precursors of aryl radicals for the direct hydroarylation of nitrones, furnishing substituted hydroxylamines, is described. The reaction proceeds under visible-light irradiation using sodium ascorbate as a reductant and acetic acid as a proton source. Light-induced E to Z isomerization of triazenes, which results in enhanced reactivity of the Z-isomer and eliminates the need for a photocatalyst, is a key feature of the method. The scope of the triazene component is limited to electron-rich and neutral aryls.
