The first example of a Pd(OAc)2-catalyzed ring-forming alkene aminoaroylation of unsaturated hydrazones and sulfonamides is described. This protocol features the use of diaryliodonium salts as both oxidants and aryl sources, thus enabling mild

A PhI(OAc)2-promoted radical cyclization of β,γ-unsaturated hydrazones and oximes has been developed for an efficient synthesis of various valuable pyrazoline and isoxazoline derivatives with satisfactory yields (up to 96%) under mild condition

A visible-light photocatalytic generation of N-centered hydrazonyl radicals has been accomplished for the first time. This approach allows efficient intramolecular addition of hydrazonyl radical to terminal alkenes, thus providing hydroamination and oxyamination products in good yields. Importantly, the protocol involves deprotonation of an N-H bond and photocatalytic oxidation to an N-centered radical, thus obviating the need to prepare photolabile amine precursors or the stoichiometric use of oxidizing reagents.
