  it has been established that triazinyl bipyridines (hemi-BTPs) and bis-triazinyl pyridines (BTPs), ligands which are currently being investigated as possible ligands for the separation of actinides from lanthanides in nuclear waste, are able to form homoleptic complexes with first row transition metals such as cobalt(IT), copper(II), iron(II), manganese(II), nickel(II) and zinc(II). The metal complexes exhibit six-co-ordinate octahedral structures and redox states largely analogous to those of the related terpyridine complexes. The reactivity of the different redox states of cobalt bis-hemi-BTP complex in aqueous environments has been studied with two-phase electrochemistry by immobilisation of the essentially water-insoluble metal complexes on graphite electrodes and the immersion of this modified electrode in an aqueous electrolyte.It was found that redox potentials for the metal-centred reactions were pH-independent whereas the potentials for the ligand-centred reactions were strongly pH-dependent. The reductive degradation of these complexes has been investigated by computational methods. Solvent extraction experiments have been carried out for a range of metals and these show that cobalt(II) and nickel(II) as well as palladium(II), cadmium(II) and lead(II) were all extracted with the ligands 1e and 2c with higher distribution ratios that was observed for americium(III) under the same conditions. The implications of this result for the use of these ligands to separate actinides from nuclear waste are discussed. (c) 2005 Elsevier Ltd. All rights reserved.

  The present invention is a method for producing a conjugated diene random copolymer comprising polymerizing at least a conjugated diene monomer using a living radical polymerization method to produce a conjugated diene polymer that comprises a halogen atom at a terminal of a polymer chain, a living radical polymerization reaction being initiated using a copper salt, a multidentate ligand that comprises a nitrogen atom having an sp 2 hybridized orbital as a coordinating atom, and an organic halide, to produce the conjugated diene polymer having a number average molecular weight (Mn) of 1,000 to 1,000,000 and a molecular weight distribution (Mw/Mn) of less than 2.0. The present invention provides a method for efficiently and inexpensively producing a conjugated diene polymer that includes a halogen atom at the terminal of the polymer chain, and has the desired molecular weight and a narrow molecular weight distribution.

  Structural data for known and newly obtained copper(II) complexes with 2,2′;6′,2″-terpyridine and substituted malonic (dimethylmalonic, 1,1-cyclopropane- and 1,1-cyclobutanedicarboxylic) acid dianions R2mal2- were used to show that the coordination environment of the metallocenter depends on the (O2C)C—C—C(CO2) angle. A chelate coordination of the R2mal2- dianion is realized for 1,1-cyclopropanedicarboxylate anion (~122.9°), while the dimethylmalonate and 1,1-cyclobutanedicarboxylate anions (107.4–110.8°) are characterized by a monodentate coordination.
