found to be an excellent ligand for copper-catalyzed N-arylation of azoles and amides with aryl halides under mild conditions. The reaction took place at 82 °C in MeCN with broad functional-group compatibility. A combination of the ligand and CuI proved to be an efficient catalytic system to promote the coupling reactions of aryl halides with azoles and amides.
Abstract A new green approach for the synthesis of amide through TBAI-catalyzed oxidative coupling of benzylbromides with amine was developed in the presence of tert-butyl hydroperoxide (TBHP) as an oxidant. Various electron-donating and withdrawing groups containing benzylbromides and various amines, were subjected to the reaction and transformed to the corresponding amide in good to excellent yields
