CuI/DMPAO-Catalyzed N-Arylation of Acyclic Secondary Amines
摘要:
DMPAO has been found to be a powerful ligand to enable copper-catalyzed coupling of aryl halides with aliphatic acyclic secondary amines take place under relatively mild conditions, and coupling of aryl halides with primary amines and cyclic secondary amines proceeds at low catalyst loading.
DMSO methylates a broad range of amines in the presence of formic acid, providing a novel, green and practical method for aminemethylation. The protocol also allows the one‐pot transformation of aromatic nitro compounds into dimethylated amines in the presence of a simple iron catalyst.
