  • Title: Visible Light Induced Brønsted Acid Assisted Pd-Catalyzed Alkyl Heck Reaction of Diazo Compounds and N-Tosylhydrazones.
    Author: Zhang Z, Kvasovs N, Dubrovina A, Gevorgyan V.
    Journal: Angew Chem Int Ed Engl; 2022 Jan 03; 61(1):e202110924. PubMed ID: 34706124.
    Abstract:
    A mild visible light-induced palladium-catalyzed alkyl Heck reaction of diazo compounds and N-tosylhydrazones is reported. A broad range of vinyl arenes and heteroarenes with high functional group tolerance, as well as a range of different diazo compounds, can efficiently undergo this transformation. This method features Brønsted acid-assisted generation of hybrid palladium C(sp3 )-centered radical intermediate, which allowed for new selective C-H functionalization protocol.
