Abstract

The photochemical reactivity of the Cu(13-AtH)/sup 2 +/ complex is noticeable only for ultraviolet irradiations (254 to 370 nm). Photolyses, carried out in the presence of various alcohols, produced aldehydes or ketones. Two Cu(II) macrocyclic complexes, one characterized as Cu(Me/sub 2/(13)monoeneN/sub 4/)/sup 2 +/, were products of the reaction. The dependence of the quantum yields on experimental variables (acid concentration, scavenger concentration, light intensity, excitation wavelength) is explained in terms of a proposed reaction mechanism. The primary product, a Cu(III) cation--ligand radical, was postulated by a comparison with the behavior already reported for Cu((14)dieneN/sub 4/)/sup 2 +/.

Photoinduced redox reactions of macrocyclic complexes with d/sup 7/ (nickel(III)) metal ions. Photoredox processes of equatorial and axial ligands

Journal Article Ferraudi, G. - Inorg. Chem.; (United States)

Ultraviolet irradiations of Ni((14)dieneN/sub 4/)(CH/sub 3/CN)/sub 2//sup 3 +/ or Ni(tet a)(CH/sub 3/CN)/sub 2//sup 3 +/ induce a reduction of the metal center and oxidation of the coordinated acetonitrile. The photoprocesses of the tet a and (14)dieneN/sub 4/ complexes have the same threshold energy for photoreactivity, E/sub th/ approx. = 79.4 kcal/mol. However, the limiting yield for Ni(tet a)(CH/sub 3/CN)/sub 2//sup 3 +/, phi = 0.03, is smaller than the yield for Ni((14)dieneN/sub 4/)(CH/sub 3/CN)/sub 2//sup 3 +/, phi = 0.15. The photooxidation of the imino groups of the macrocycle has been observed in flash photolyses of Ni((14)dieneN/sub 4/)(CH/sub 3/CN)/submore »« less

Polynuclear copper-lanthanide complexes with amino alcohol ligands. Syntheses, structures, and magnetic and spectroscopic studies of Cu{sup II}(bdmmp){sub 2}(H{sub 2}O), Pr{sup III}Cu{sup II}(bdmmp)(bdmmpH)({mu}-OH)(hfacac){sub 3}, [La{sup III}Cu{sup II}(bdmmp)(bdmmpH)({mu}-OH)(O{sub 2}CCF{sub 3}){sub 3}]{sub 2}, and Cu{sup II}{sub 4}(bdmmp){sub 2}({mu}{sub 4}-O)(O{sub 2}CCF{sub 3}){sub 4}, (bdmmpH = 2,6-bis[(dimethylamino)methyl]-4-methylphenol; hfacac = hexafluoroacetylacetonato)

Journal Article Chen, L. ; Breeze, S.R. ; Rousseau, R.J. ; ... - Inorganic Chemistry

The syntheses of polynuclear copper(II)-lanthanide(III) complexes using the 2,6-bis[(dimethylamino)methyl]-4-methylphenolato ligand (bdmmp) have been investigated. The reaction of Cu(OCH{sub 3}){sub 2} with 2 equiv of bdmmpH in THF yields a mononuclear copper complex Cu(bdmmp){sub 2}(H{sub 2}O) (1), which subsequently reacts with 1 equiv of Pr(hfacac){sub 3} or La(O{sub 2}CCF{sub 3}){sub 3} (hfacac = hexafluoroacetylacetonato) to produce two heteronuclear complexes Pr{sup III}-Cu{sup II}(bdmmp)(bdmmpH)(OH)(hfacac){sub 3} (2) and [La{sup III}Cu{sup II}(bdmmp)(bdmmpH)(OH)(O{sub 2}CCF{sub 3}){sub 3}]{sub 2} (3). The reaction of Cu{sub 4}(bdmmp){sub 2}({mu}{sub 4}-O)(O{sub 2}CCF{sub 3}){sub 4} (4). The structures of compounds 1-4 have been determined by single-crystal X-ray diffraction analysis.

Binuclear complexes of macrocyclic ligands: electrochemical and spectral properties of homobinuclear Cu/sup II/Cu/sup II/, Cu/sup II/Cu/sup I/, and Cu/sup I/Cu/sup I/ species including an estimated intramolecular electron transfer rate

Journal Article Gagne, R.R. ; Koval, C.A. ; Smith, T.J. ; ... - J. Am. Chem. Soc.; (United States)

Electrochemical techniques were employed to study electron transfer properties of a binuclear copper--macrocyclic ligand complex and to prepare several reduced derivatives. The complex, Cu/sup II/Cu/sup II/L(ClO/sub 4/)/sub 2/.2H/sub 2/O, was prepared by condensing 1,3-diaminopropane with 5-methyl-2-hydroxyisophthalaldehyde and Cu(ClO/sub 4/)/sub 2/.6H/sub 2/O. The Cu/sup II/Cu/sup II/ complex was reduced in successive, quasi-reversible, one-electron steps at - 0.52 and - 0.91 V vs. NHE. Constant-potential electrolysis was employed to prepare the reduced species, Cu/sup II/Cu/sup I/L(ClO/sub 4/) and Cu/sup I/Cu/sup I/L, both of which were isolated and fully characterized. The mixed-valence species, Cu/sup II/Cu/sup I/L/sup +/, is stable in oxygen-free solutions (conproportionationmore »« less

Photoinduced electron-transfer reactions of ruthenium(II) complexes. 1. Reductive quenching of excited Ru(bpy) sub 3 sup 2+ by aromatic amines

Journal Article Kitamura, Noboru ; Kim, Haengboo ; Okano, Sumio ; ... - Journal of Physical Chemistry; (USA)

The rate constants (k{sub q}) and activation parameters for reductive quenching of *Ru(bpy){sub 3}{sup 2+} (bpy = 2,2{prime}-bipyridine) by 19 aromatic amines were determined in acetonitrile. The activation enthalpies ({Delta}H{sub 23}{double dagger}) increased from +1 to +6 kcal/mol with decreasing k{sub q} while the activation entropies were almost constant around {minus}15 eu for all quenchers except for those of highly exoergic reactions. The mechanism of the reductive quenching is discussed on the basis of k{sub q} as well as of the activation parameters. The quenching was shown to depend on the nature of the aromatic amine; the quenching by tertiarymore »« less

Transannular oscillation of metal centers in the pendant arm macrocyclic complex (1,4,8,11-tetrakis(2-hydroxyethyl)-1,4,8,11-tetraazacyclotetradecane)mercury(II) and its lead(II) analogue. NMR study of the sup 13 C natural abundance and specifically enriched complexes

Journal Article Clarke, P. ; Lincoln, S.F. ; Wainwright, K.P. - Inorganic Chemistry; (USA)

A {sup 13}C NMR study of (1,4,8,11-tetrakis(2-hydroxyethyl)-1,4,8,11-tetraazacyclotetradecane)mercury(II) and its lead(II) analogue, (M(THEC)){sup 2+} (M = Hg, Pb), in CD{sub 3}OD, shows that the most probable structure of these complexes in solution incorporates the 1,4,8,11-tetraazacyclotetradecane ring in the trans III configurations with the metal center above the tetraaza plane and trigonal-prismatically coordinated by four ring nitrogens and two hydroxyethyl pendant arms attached to either end of the same 1,3-diaminopropane moiety. Dynamic {sup 13}C NMR studies of (M(THEC)){sup 2+} are consistent with a rapid pairwise intramolecular exchange of the hydroxyethyl arms between mono- and bidentate coordination simultaneously with the oscillation of M(II)more »« less
