| Abstract
| - Three novel tetradentate ligands with quinoline functionalities, 1,2,4,5-tetrakis(6-ethylquinolin-8-yl)benzene, 1,2,4,5-tetrakis(6-tert-butylquinolin-8-yl)benzene, and 1,2,4,5-tetrakis(6-(trifluoromethoxy)quinolin-8-yl)benzene, were synthesized through a three-step protocol and fully characterized by NMR spectroscopic, elemental, and X-ray diffraction analyses. The dinuclear dimethylplatinum(II) complexes of these ligands readily activate C−Cl bonds of CHCl3 at ambient temperature, leading to the formation of the corresponding dinuclear Pt(IV) complex. In these reactions, the central phenyl rings of the tetradentate ligands are reduced to cyclohexadiene dianions and still retain their planarity.
- We report the syntheses and full characterization of three novel tetradentate ligands with quinoline functionalities. Owing to their geometry, the dinuclear dimethylplatinum(II) complexes of these ligands react readily with CHCl3 under ambient conditions to afford the corresponding dinuclear Pt(IV) complexes. In these reactions, the central phenyl rings of the ligands are jointly reduced by the metal centers into cyclohexadiene dianions and still retain their planarity.
