  Structure-dependent spectroscopic and redox properties of copper(I) complexes with bidentate iminopyridine ligands

  摘要：

  A series of iminopyridine ligands; cyclopropylpyridin-2-ylmethyleneamine (A), cyclopentylpyridin-2-ylmethyleneamine (B), cyclohexylpyridin-2-ylmethyleneamine (C), and cycloheptylpyridin-2-ylmethyleneamine, (D) and their copper(I) complexes, [Cu(L)(2)](+) (1a-1d) and [Cu(L)(PPh3)(2)](+) (2a-2d) have been synthesized and characterized by CHN analyses, H-1 NMR and IR and UV-Vis spectroscopy. Structures of 1a, 1b, 1c and 2a were determined by X-ray crystallography. The coordination polyhedron about the Cu-I center in the complexes is best described as a distorted tetrahedron. The dihedral angles between the least-squares planes of the chelate ligands show considerable variation from 86.1 degrees in 1a to 68.3 degrees in 1b, indicating the importance of packing forces in the crystalline environment. The UV-Vis spectra of the complexes are characterized by first metal to ligand charge transfer bands increasing in wavelength with increasing size of the ring substituents in the ligands, except for the cyclopropyl compounds (1a and 2a), in good agreement with the variation of the dihedral angles between the ligand planes. Cyclic voltammetry of the complexes indicates a quasireversible redox behavior for the complexes. The bulkier ligands (PPh3) inhibit the geometric distortion within the oxidized form and the redox potentials of complexes 2a-2d are shifted to more positive values, therefore. (C) 2009 Elsevier B.V.

  Strong Coordination of Tetraphenylborate Anion to Copper(I) Bipyridine and Phenanthroline-Based Complexes and Its Effect on Catalytic Activity in the Cyclopropanation of Styrene

  摘要：

  The synthesis, characterization, and cyclopropanation activity of tetrahedral copper(I) complexes with bipyridine- and phenanthroline-based ligands containing strongly coordinated tetraphenylborate anions are reported. Cu-I(bpy)(BPh4), Cu-I(phen)(BPh4), and Cu-I(3,4,7,8-Me(4)phen)(BPh4) complexes are the first examples in which the BPh4- counterion chelates a transition metal center in bidentate fashion through eta(2) pi interactions with two of its phenyl rings.

  reactions of phenols are currently intensively studied. Herein, new copper catalysts for the C−C coupling reaction of phenols using dioxygen as a green oxidizing reagent are reported. By using redox‐active guanidine ligands, the activity as well as chemoselectivity in the cross‐coupling reaction of non‐complementary phenols (between an electron‐rich phenol and a less nucleophilic second phenol) is significantly
