Cobalt-Catalyzed Radical Hydroamination of Alkenes with N-fluorobenzenesulfonimides.
Angewandte Chemie, 2021An efficient and general radical hydroamination of alkenes using Co(salen) as catalyst, N-fluorobenzenesulfonimide (NFSI) and its analogues as both nitrogen source and oxidant was successfully disclosed. A variety of alkenes, including aliphatic alkenes,

Electrochemical Synthesis of Allylic Amines from Terminal Alkenes and Secondary Amines.
Journal of the American Chemical Society, 2021Allylic amines are valuable synthetic targets en route to diverse biologically active amine products. Current allylic C-H amination strategies remain limited with respect to the viable N-substituents.

Enantioselective Cyanofunctionalization of Aromatic Alkenes via Radical Anions.
Journal of the American Chemical SocietyAlkene radical ions constitute an integral and unique class of reactive intermediates for the synthesis of valuable compounds because they have both unpaired spins and charge.

Catalytic Allylation of Aldehydes Using Unactivated Alkenes.
Journal of the American Chemical Society, 2020Simple feedstock organic molecules, especially alkenes, are attractive starting materials in organic synthesis because of their wide availability. Direct utilization of such bulk, inert organic molecules for practical and selective chemical reactions ...

The α-C–H functionalization of piperidine catalyzed by tantalum complex 1 to produce amine 2 was developed (Org. Lett. 2013, 15, 2182) by Laurel L. Schafer at the University of British Columbia. An asymmetric diamination of diene 3 with diaziridine reagent 4 under palladium catalysis to furnish cyclic sulfamide 5 was developed (Org. Lett.

Radical-Mediated Strategies for the Functionalization of Alkenes with Diazo Compounds.
Journal of the American Chemical Society, 2020One of the most common reactions of diazo compounds with alkenes is cyclopropanation that occurs through metal carbene or free carbene intermediates. Alternative functionalization of alkenes with diazo compounds is limited, and methodology for the addi ...

Recent advances in copper-catalysed radical-involved asymmetric 1,2-difunctionalization of alkenes.
Chemical Society Reviews, 2019The radical-involved 1,2-difunctionalization of alkenes has developed into a robust tool for preparation of complex organic molecules. Despite significant advances in this area, the catalytic asymmetric version still remains a challenging task mainly due

Cycloadditions are among the most efficient chemical processes, combining atom economy, stereospecificity, and the ability to generate molecular complexity in a single step. Aromatic rings would in principle be ideal reaction partners, as they contain, at least from the topological point of view, both olefinic and diene subunits; however, the stability
