An in situ generated oxidation species of nickel quinolinylpropioamide intermediate was produced. Characterization by X‐ray absorption near edge structure (XANES) and EPR provides complementary insights into this oxidized nickel species. With aliphatic amides and isocyanides as substrates, a nickel‐catalyzed facile synthesis of structurally diverse five‐membered lactams could be achieved.
