Abstract
Catalytic dehydrogenation of hydrazine was achieved over iminopyridine ligated ruthenium–arene complexes, where the release of H2 gas, as confirmed by GC‐TCD, from hydrazine depends on reaction temperature, base, and solvents. NMR and MS studies indicated an in situ generation of a hydrazine‐coordinated ruthenium species, a key intermediate of hydrazine dehydrogenation, via a coordination‐assisted activation pathway.
