Isolable Monocyclic N ‐Heterocyclic Radicals Supported by Rare‐Earth Organometallics

) in 2-Gd, while compound 4-Dy exhibits slow magnetic relaxation. Furthermore, the initial exploration on reactivity revealed the potential ability of the pyridine radical to activate inert bonds. Those results contribute to a better understanding of highly reactive species involving monocyclic heterocyclic radicals.
