A selective N-arylation of cyclic amides and amines in DMF and water, respectively, catalysed by CuII/Al2O3 has been achieved. This protocol has been employed for the synthesis of a library of arenes bearing a cyclic amide and an amine moiety at two ends, including a few scaffolds of therapeutic importance. The mechanism has been established based on detailed electron paramagnetic resonance (EPR) spectroscopy, X-ray photoelectron spectroscopy (XPS), UV diffuse reflectance spectroscopy (DRS) and inductively coupled plasma-mass spectrometry (ICP-MS) studies of the catalyst at different stages of the reaction. The CuII/Al2O 3 catalyst was recovered and recycled for subsequent reactions. One over the other: A selective N-arylation of cyclic amides and amines in DMF and water, respectively, catalyzed by CuII/Al2O3 has been achieved (see scheme). This protocol has been employed for the synthesis of a library of arenes bearing cyclic amide and amine moieties at two ends including a few scaffolds of therapeutic importance. The mechanism has been established based on detailed spectroscopic studies (FG=functional group). Copyright

(Chemical Equation Presented) An efficient copper-catalyzed multicomponent reaction of phenols, amides, and 4-bromphenyl iodide was developed that uses commercially available N,N-dimethylglycine as the ligand. This multicomponent reaction proceeds in moderate to good yields for a range of phenols and amides. The simple experimental procedure and high levels of functional group compatibility make this method attractive for applications on pesticides.
Scope and selectivity in palladium-catalyzed directed C-H bond halogenation reactions

Palladium-catalyzed ligand directed C-H activation/halogenation reactions have been extensively explored. Both the nature of the?directing group and the substitution pattern on the arene ring of the substrate lead to different reactivity profiles, and often different and complementary products, in the presence and absence of the catalyst.
