The N-arylation of several types of amidic nitrogen atoms, including those found in carboxamides, sulfonamides, carboxylic acid imides, mixed carboxylic-sulfonic imides and hydantoin systems was carried out by treatment of their sodium salts with p-tolyllead triacetate in the presence of copper (II) acetate.

copper-catalyzed Goldberg reaction at 90–110 °C between aryl bromides and amides providing the desired products in good to excellent yields has been developed using N,N-dimethylglycine as the ligand. The reaction is tolerant toward a wide range of amides and a variety of functional group substituted aryl bromides. In addition, hindered, unreactive aromatic and aliphatic secondary acyclic amides, known to be poor
-Dibenzylethylenediamine is presented as a new, efficient, and versatile bidentateligand suitable for the copper catalyzed formation of the C-N bond. This bidentateligand has been demonstrated to facilitate the copper catalyzed cross-coupling reactions of aryl iodides with amides to afford the desired products in good to excellent yields.
coupling of aryliodides with aliphatic alcohols and phenols that does not require the use of alkoxide bases is described. This C-O bond forming procedure shows that the combination of air stable Cul and 1,10-phenanthroline in the presence of KF/Al 2 O 3 comprises an extremely efficient and general catalyst system for the etherification of aryliodides. Different functionalized aryliodides were coupled
