The synthesis and characterization, spectroscopic, and biological studies of 2-acetylferrocenyl-4phenylthiosemicarbazone, 2-acetylferrocenyl-4-methylthiosemicarbazone, 2-acetylpyridine-2thiophenecarboxylsemicarbazone and 2-acetylferrocenyl-2-thiophenecarboxylsemicarbazone with copper(II) chloride are reported here. The ligands were synthesized by condensation reaction of appropriate carbonyl an...

Reduction of oxi me fu nctionality to amine is an important synthetic transformation . As ox imes are stable derivatives of carbonyl compounds, subsequent reduction to amines is an attractive two-step procedure for reductive ami nation . Red uction of oximes to amines can be performed by hydride reducing agents or by catalytic hydrogenation.' Among hydride reducing agents, lithium aluminium hyd...

Atomic-scale integration of polyether molecules and copper(II) chloride layers in a two-dimensional perovskite affords, to the best of our knowledge, the first example of extended Li(+) cycling in a metal chloride electrode. The hybrid can cycle over 200 times as a cathode in a lithium battery with an open-circuit voltage of 3.2 V. In contrast, CuCl2 alone or the precursors to the hybrid cannot...

the nanoparticles of gold doped with various percentage of copper (cu 10%, 25%, 75%) were synthesized by wet-chemical method at room temperature. copper (ii) sulfate and gold (iii) chloride trihydride was taken as the metal precursor and ascorbic acid as a reducing agent and anhydride maleic as surfactant. the reaction is performed with high-speed stirring at room temperature under nitrogen atm...

Reactions of 2,2'-pyridil (pyCOCOpy) with CuCl(2) . 2H(2)O and CuBr(2) in EtOH yielded the mononuclear complex [Cu(pyCOOEt)(2)Cl(2)] . H(2)O (1) and the one-dimensional, mixed-valence complex [Cu(2) (I)Cu(II)(pyCOOEt)(2)Br(4)](n) (2), respectively. Both complexes crystallize in the triclinic space group P 1 . The lattice constants are a = 8.382(2), b = 9.778(2), c = 7.814(2), alpha = 101.17(1),...

Six series of structurally different mono- and binuclear copper(II) complexes 5-10 were obtained by reacting N-(2-pyridyl)imidazolidin-2-ones (1a-l), N,N'-bis(2-pyridyl)imidazolidin-2-ones (2a,b), N-acyl-N'(2-pyridyl)imidazolodin-2-ones (3a-j) and N-(2-pyridyl)imidazolidine-2-thiones (4a-g) with copper(II) chloride at an ambient temperature. The coordination modes of the complexes obtained were...

The reaction of mercury(II) chloride dihydrate, propane-1,3-diamine and 4-hydroxy-pyridine-2,6-dicarboxylic acid in a 1:1:1 molar ratio in aqueous solution, resulted in the formation of the title compound, (C(3)H(12)N(2))[Hg(C(7)H(3)NO(5))Cl(H(2)O)](2)·4H(2)O or (pnH(2))[Hg(hypydc)Cl(H(2)O)](2)·4H(2)O (where pn is propane-1,3-diamine and hypydcH(2) is 4-hydroxy-pyridine-2,6-dicarboxylic acid). ...

introduction: among soil species earthworms are ubiquitous, abundant and important for soil processes, constituting the largest terrestrial faunal biomass and are also impacted by soil pollutants. the primary purpose of this study was to determine whether changes in earthworm biomass and behavior could serve as a good indicator for copper toxicity in soil systems. another aim of the study was t...
