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 Cu-II ions, exhibiting excellent catalytic activity in promoting the Chan-Lam cross-coupling reaction between biologically active amines and arylboronic acids. The performance of this catalyst is also evident from its broad substrate scope, high stability, real heterogeneity, mild reaction conditions and reusability without loss of activity. The observed results will provide additional scope on the design and catalytic applications of this emerging class of materials.
