“…Recently, Katritzky pyridinium salts, easily prepared from the condensation of primary amines with commercially available pyrylium salts, have emerged as a powerful tool for the generation of alkyl radical species. 3 Watson, 4 Glorius, 5 Aggarwal, 6 Shi, 7 Gryko, 8 Xiao, 9 Martin, 10 Rueping, 11 and Molander 12 have demonstrated the utility of Katritzky salts to form various types of C-C and C-B bonds via deaminative cross-coupling under Nicatalyzed or photomediated conditions (Scheme 1a). Despite the impressive achievements in this eld, a synthetic method that efficiently transforms an amine functionality into a carbonyl group via a deaminative radical pathway is still underexplored.…”
