Pyridine <i>N</i> -oxides as HAT reagents for photochemical C–H functionalization of electron-deficient heteroarenes
Łukasz W. Ciszewski, Dorota Gryko
Abstract
-oxide precludes the need for a photocatalyst. The developed method allows for a broad range of radical precursors to be used, namely alkanes, alkenes, amides, and ethers, for efficient alkylation of azines.
