Synthesis of Symmetrical Triaryl Amines by Nano-CuO Catalyzed Buchwald-Hartwig Cross-coupling Reaction: NH۲-Thiadiazole as a New N-source

The one-pot synthesis of symmetrical triaryl amines using aryl halides and ۵-Methyl-۱,۳,۴-Thiadiazole-۲-Amine as a nitrogen-transfer reagent is reported. Copper oxide nanoparticles that does not require the presence of any additional ligand, improved rate and facility of the synthesis of triaryl amines. The introduction of a new N-source, using green solvents PEG/H۲O, normal atmospheric conditions and excellent yields under mild reaction conditions are other important features of this work.
