Structural aspects of copper catalyzed atom transfer radical polymerization

The mononuclear mixed ligand copper(II) complexes of the type [Cu(l-tyr)(diimine)](ClO4), where tyr is l-tyrosine and diimine is 2,2′-bipyridine (bpy) (1), 1,10-phenanthroline (phen) (2), 5,6-dimet...

Induction of cell death by ternary copper(II) complexes of L-tyrosine and diimines: role of coligands on DNA binding and cleavage and anticancer activity.

The kinetics of atom transfer radical polymerization (ATRP) of methyl acrylate (MA) is discussed. MA polymerizations were carried out under homogeneous conditions using CuBr/4,4‘-di(5-nonyl)-2,2‘-bipyridine (dNbpy) as the catalyst. Plots of ln([M]o/[M]) vs time and molecular weight evolution vs conversion showed a linear dependence, indicating a constant number of propagating species throughout the polymerization as well as a negligible contribution of termination or transfer reactions. The dependence of the rate of polymerization on the concentrations of initiator, catalyst, Cu(II), and temperature are presented. The equilibrium constant between active and dormant species, Keq = 1.2 × 10-9 at 90 °C is much smaller than in the ATRP of styrene or methyl methacrylate. On the basis of an Arrhenius plot, the apparent enthalpy of activation for homogeneous ATRP of MA ΔH‡app = 27.5 kcal/mol corresponds to an enthalpy of equilibrium ΔH0eq = 23 kcal/mol, which is much higher than in the ATRP of styrene or methyl ...

Interaction of mixed ligand copper(II) complexes with CT DNA and BSA: Effect of primary ligand hydrophobicity on DNA and protein binding and cleavage and anticancer activities

Mixed ligand copper(II) complexes of 1,10-phenanthroline with tridentate phenolate/pyridyl/(benz)imidazolyl Schiff base ligands: covalent vs non-covalent DNA binding, DNA cleavage and cytotoxicity.

The crystal structure of [Cu(bipy)2Cl]BF4(I)(bipy = 2,2′-bipyridyl) has been determined using diffractometer data collection. It was solved by the heavy-atom method and successive Fourier difference syntheses. Compound (I) crystallises in the monoclinic space group P21/n with a= 16.187(4), b= 12.177(3), c= 10.793(3)A, β= 104.49(3)°, Z= 4, and R= 0.058 for 1 451 unique reflections. The CuN4Cl chromophore involves a square-based-pyramidal distorted trigonalbipyramidal stereochemistry. The extent of the square-pyramidal distortion is mirrored in the twin-peaked electronic reflectance spectrum, with absorption maxima at 10 100 and 13 900 cm–1. The structure of complex (I) is compared with those of a series of eight cation distortion isomers of [Cu(bipy)2Cl]Y which are related by a structural pathway. The nine complexes have been subjected to scatter-plot and factor-group analysis and the feasibility of extending the structural pathway to include two [Cu(bipy)2Br]+ and two [Cu(bipy)2I]+ complexes is examined.
