Despite significant progress, copper-catalyzed, directed C−H activation to form C-heteroatom bond is a challenging problem due to strong chelation with the directing group and the incoming nucleophile. Therefore, stoichiometric copper salt was used

Despite significant progress, copper-catalyzed/mediated C-H amination reactions with electron-rich anilines remain an unsolved problem due to catalyst deactivation and deleterious side reactions. Herein, we report a copper(II)-mediated C(sp(2))-H ami

We report here a practical method for the ortho C–H hydroxylation of benzamides with inexpensive copper(II) acetate monohydrate and a pyridine ligand. An intra- and intermolecular ligand combination was explored to achieve regio- and chemoselective
