An efficient and general selective method for the synthesis of 8-aminoquinoline derivatives has been disclosed through transition metal direct C–N coupling from fluoroquinolines and arylamines. Significantly, good chemo- and regio-selectivity was observed for polyfluoroquinolines in which only C–F bond on 8-substituted position was broken. Thus, this methodology proves its value as an inexpensive and

The synthesis of a novel mesoporous covalent imine polymeric (MCIPs) material, involving simple Schiff‐base chemistry, is reported. This highly functionalised nitrogen‐rich material acts as a good support for immobilising CuII ions, exhibiting excellent catalytic activity in promoting the Chan–Lam cross‐coupling reaction between biologically active amines and arylboronic acids. The performance of this
