Frontispiece: Hydrogen Atom Transfer Reactions via Photoredox Catalyzed Chlorine Atom Generation
Graphical Abstract
Photoredox Catalysis. Highly reactive chlorine atoms for C−H functionalizations are generated by L. Barriault and co-workers in their Communication on page 15664 through reductive quenching of *[Ir(dF(CF3)ppy)2(dtbbpy)]+ with chloride.
