The first zinc-catalyzed oxidativeamidation of benzylalcohols has been developed. Both aliphatic and aromatic amines can be tolerated and applied in this reaction. Various amides were prepared in good yields undersolvent-free and mild conditions.

in the presence of DTBP and TBAI to afford the transamidated products in good yields. The reactions were conducted underaqueousconditions and good functional group tolerance was achieved. Both aliphatic and aromatic primary amines displayed good activity under metal-free conditions. A radical reaction pathway is proposed.

Direct transamidation of secondaryamides was developed via nickel catalysis. In the presence of trimethylsilyl chloride and manganese, Ni(diglyme)Cl2 with a Briphos ligand efficiently promoted the transamidation of N-aryl benzamide derivatives with primary amines to afford the corresponding secondaryamides in moderate to good yields. Primary amines bearing electron-donating groups gave higher yields
