Nickel-(II)-Catalyzed N-Formylation and N-Acylation of Amines

A highly efficient protocol of Ni(II) metal complex, [Ni(quin)(2)], catalyzing N-formylation and N-acylation of amines with moderate to excellent yields, using N,N-dimethylformamide and N,N-dimethylacetamide in the presence of imidazole, is described here. The protocol shows broad substrate scope for aliphatic, aromatic, and heterocyclic amines.
