Journal ArticleDOI
Visible light-mediated atom transfer radical addition via oxidative and reductive quenching of photocatalysts.
TL;DR: Modifications of the reaction conditions allowed for the efficient ATRA of perfluoroalkyl iodides onto alkenes and alkynes utilizing the reductive quenching cycle of [Ru(bpy)(3)]Cl(2) with sodium ascorbate as the sacrificial electron donor.
Journal ArticleDOI
Photoredox activation and anion binding catalysis in the dual catalytic enantioselective synthesis of β-amino esters
Giulia Bergonzini,Corinna S. Schindler,Carl-Johan Wallentin,Eric N. Jacobsen,Corey R. J. Stephenson +4 more
TL;DR: The enantioselective oxidative C-H functionalization of tetrahydroisoquinoline derivatives is achieved through the merger of photoredox and asymmetric anion-binding catalysis and introduces a potentially general approach to asymmetric transformations in oxidative photocatalysis.
Journal ArticleDOI
Photocatalytic decarboxylative reduction of carboxylic acids and its application in asymmetric synthesis.
TL;DR: The application of this method to the synthesis of enantioenriched 1-aryl-2, 2,2,2-trifluoroethyl chiral amines starting from natural α-amino acids further testifies to the utility of the developed photocatalytic decarboxylative reduction protocol.
Journal ArticleDOI
Acyl Radicals from Aromatic Carboxylic Acids by Means of Visible-Light Photoredox Catalysis
TL;DR: By the transient generation of a reactive anhydride intermediate, this redox-neutral approach offers a mild and rapid entry to high-value heterocyclic compounds without the need of UV irradiation, high temperature, high CO pressure, tin reagents, or peroxides.
Journal ArticleDOI
Active Species and Mechanistic Pathways in Iron-Catalyzed C–C Bond-Forming Cross-Coupling Reactions
TL;DR: In this article, the authors present mechanistic pathways of iron-mediated cross-coupling reactions of organohalides and Grignard reagents and discuss the evidence documented in the literature that distinguishes whether such pathways proceed via single- or double-electron processes.
