Mn(II)-Catalyzed N -Acylation of Amines

Ma, Juan,Zhang, Jingyu,Gong, Hang

, p. 693 - 703 (2019)

A practical protocol has been developed here for the Mn(II)-catalyzed N -acylation of amines with high yields using N, N -dimethylformamide and other amides as the carbonyl source. The protocol is simple, does not require any acid, base, ligand, or other additives, and encompasses a broad substrate scope for primary, secondary, and heterocyclic amines.
