A Cu(OAc)2-mediated C-Hamidation and amination of arenes and heteroarenes has been developed using a readily removable directing group. A wide range of sulfonamides, amides, and anilines function as amine donors in this reaction. Heterocycles present in both reactants are tolerated, making this a broadly applicable method for the synthesis of a family of inhibitors including 2-benzamidobenzoic acids

Microwave-induced syntheses of sulfonamides, without using base under solvent-free conditions, have been developed. The process finds its utility because of its simple operational procedure and high yields. Moreover, the process is fast and accommodative to different substituents on aromatic as well as heteroaromatic rings rendering sulfonamides (28 examples).
