Transition metal catalyzed C-N cross coupling reactions are considered to be extremely powerful and versatile methods in the synthesis of pharmaceuticals,<sup> </sup>optical devices, and materials. The conventional route for N- arylation of N-nucleophiles with aryl halides is the Ullmann type coupling reactions. However they associated with the limitations of harsh conditions, and long reaction times. Great efforts have been made to minimize these problems, and one of them is Buchwald – Hartwig amination. The reaction requires palladium-based catalysts with external ligands and proceeds under milder conditions. We also have various reports of Pd catalyzed C-N bond formation by coupling aryl halides with various N-nucleophiles. However, the high cost of Pd and use of external ligands makes it difficult to apply these reactions in the industrial scale. Also, most of these ligands are hard to synthesize and these catalytic systems are not applicable to all kind of N-nucleophiles. So, we are in a desperate need of common catalytic system that can be applicable to all kind of N- Nucleophiles. Here we are reporting a copper (II) catalytic system that applicable to coupling of aryl halides with various N-nucleophiles such as cyclic imides and N-formyl amines. The highlights of our reactions include, short reaction timings, broad substrates, in expensive catalyst
