Assembly of Functionalized Organic Fragments via Reductive Activation and (Cross)‐Coupling of C2H4, CO, CO2 and/or H2 Using a Magnesium‐Dinitrogen Complex

open access: yesAngewandte Chemie, Volume 137, Issue 19, May 5, 2025.
A dimagnesium/dipotassium complex of N2 acts as a “masked” source of a dimagnesium(I) diradical in formal reductive coupling and cross‐coupling reactions involving various combinations of the simple gaseous small molecules, C2H4, CO, CO2, and H2. A range of more complex “value‐added” organic fragments have been accessed from these processes.
