A variety of substituted tris(pyridyl) frameworks, as well as a pentakis(pyridine) system, are conveniently accessible in a one-pot synthesis, which consists of two sequential nucleophilic aromatic substitutions, employing substituted pyridine precursors.
alkoxyl groups in mononuclear copper(II) complexes of N,O ligands L1 and L2, results in dinuclear complexes sharing symmetrical Cu2O2 cores. Mono- and binuclear complexes thus derived have been characterised with respect to molecular structure (XRD), electronic structure (UV-Vis, 1H-NMR, and EPR; density functional methods) and catalytic performance as models of catecholoxidase. The binuclear complexes
