In this article we have demonstrated a palladium-catalyzed methodology for the direct coupling of quinoline-8-carboxaldehyde with aryl iodide and/or aryl diazonium salt to synthesize 8-aryloylquinoline. Reverse reactivity was observed by changing the arylating source; electron-donating group-substituted aryl iodide favors the reaction and provided a very good yield of the desired ketone, whereas electron-withdrawing group-substituted aryl diazonium salt provided a better yield

Copper/Manganese Oxide Catalyzed Regioselective Amination of Quinoline N-Oxides: An Example of Synergistic Cooperative Catalysis
In this article we present a simple Cu-MnO heterogeneous catalyst for the synthesis of 2-amino quinoline via direct C-H amination of quinoline oxides with an amine under air, the most benign oxidant. The key advantages such as the reusability of the catalyst several times, the reaction is a ligand, base and, additive-free, and carried out under aerobic conditions.

Copper(II) mediated ortho C–H alkoxylation of aromatic amines
In this article we present an unprecedented hindered alkoxylation of picolinamide attached aromatic amines using economic copper salt and organic peroxide to get highly desirable α-tertiary alkyl aryl ethers. Synthesis of hindered alkyl aryl ether derivatives (R-O-Ar) remains a huge challenge and highly desirable in organic and medicinal chemistry because extensive substitution on the ether bond prevents the undesired metabolic process and thus avoids rapid degradation in vivo.
