Regioselective Introduction of Heteroatoms at the C-8 Position of Quinoline <i>N</i>-Oxides: Remote C–H Activation Using <i>N</i>-Oxide as a Stepping Stone
Reported herein is the metal-catalyzed regioselective C-H functionalization of quinoline N-oxides at the 8-position: direct iodination and amidation were developed using rhodium and iridium catalytic systems, respectively. Mechanistic study of the amidation revealed that the unique regioselectivity is achieved through the smooth formation of N-oxide-chelated iridacycle and that an acid additive plays

Abstract Several new complexes of lanthanide(III) nitrates, perchlorates, chlorides and trifluoromethanesulfonates with the ligand 2,2′-biquinolyl-N,N′-dioxide and the parent 2,2′-biquinolyl, have been prepared and characterized. Information on the electron-donating power of the ligands and the geometry of the complexes has been inferred from the absorption and emission ff spectra. Uncommonly high

Abstract Complexes of cobalt(II), nickel(II) and copper(II) ions with 2,2′-biquinolyl-N,N′-dioxide have been prepared and characterized. Tris(2,2′-biquinolyl-N,N′-dioxide) complexes were obtained with cobalt(II) and nickel(II) ions while bis(2,2′-biquinolyl-N,N′-dioxide) complexes formed with the copper(II) ion. Electronic and EPR spectra indicated octahedral structures for cobalt(II) and nickel(II) complexes

Abstract The absorption and emission spectra of several complexes of neodymium(III) and europium(III) ions have been examined in order to obtain reliable information relating to coordination number, nature of bonding and symmetry around the lanthanide ion. It has been found that steric factors may force the polyhedron of coordination towards geometries less favourable by ligand–ligand repulsion. In
