A series of catalysts based on supportedcoppernanoparticles have been prepared and tested in the amide bond formation from tertiary amines and acid anhydrides, in the presence of tert‐butyl hydroperoxide as an oxidant. Coppernanoparticles on zeolite Y (CuNPs/ZY) was found to be the most efficient catalyst for the synthesis of amides, working in acetonitrile as solvent, under ligand‐ and base‐free
