Cross‐Coupling of Gaseous Alkanes with (Hetero)Aryl Bromides via Dual Nickel/Photoredox Catalysis

Angewandte Chemie, Volume 137, Issue 2, January 10, 2025.
A catalytic methodology for the direct cross‐coupling of gaseous alkanes with (hetero)aryl bromides through the combination of metallaphotoredox‐mediated hydrogen atom transfer and nickel catalysis is reported. The method provides an efficient platform for the conversion of these abundant chemical feedstocks into high‐value alkyl(hetero)arenes and ...
