Development of reactions using ethynylbenziodoxol(on)e (EBX) reagents. (a) Alkynylation of carbon- and heteroatom-based nucleophiles with EBX reagents. (b) Palladium-catalyzed reaction of N-aryl imines and EBX reagents to make multisubstituted furans. (c) Upper: palladium-catalyzed reaction of EBX reagents and carboxylic acids; lower: palladium-catalyzed three-component reaction of EBX reagents, carboxylic acids, and imines. (d) Copper-catalyzed oxy-alkynylation of diazo compounds using EBX reagents. (e) This work: reactions of EBX reagents and phenols under visible light irradiation. Nu: nucleophile.
