We report the synthesis and characterization of several novel aminopyridine - L-amino acid derived Cu(II)-complexes. The ligands are prepared by a one-pot reductive alkylation of the L-amino acid scaffold and the respective aminopyridine Cu(II)-complexes were obtained by reaction with CuCl2 or Cu(acetato)2. All compounds were characterized by spectroscopic techniques, as well as ESI-MS. Two of ...
Two hydrogen-bonds from geometrically constrained OH groups to coordinated oxygen donors shift the reduction potential of a Cu(II) complex by +270 mV as compared to the structurally analogous reference complex missing the OH groups.
Metal-catalyzed C–N cross-coupling generally forms C−N bonds by reductive elimination from metal complexes bearing covalent C- and N-ligands. We have identified a Cu-mediated that uses dative N-ligand in the bond-forming event, which, contrast to conventional methods, generates reactive cationic products. Mechanistic studies suggest process operates via transmetalation of an aryl organoboron Cu...
