Thermal decomposition of bis(4-bromo-2,6-dichlorophenoxo)-(N,N,N',N'-tetramethylethylenediamine)copper(II) complex in toluene, bis(4-bromo-2,6-dichlorophenoxo)(N,N-dimethylformamide)copper(II) complex in N,N-dimethylformamide and bis(4-bromo-2,6-dichlorophenoxo)dimethyl sulfoxide)copper(II) complex in dimethyl sulfoxide was achieved at 70-degrees-C. 4-Bromo-2,6-dichlorophenol derivatives prefer 1,4-addition to 1,2-addition, leading to highly linear polymers irrespective of the substituted ligands. The complexes were characterized by IR spectroscopy and C, H, N elemental analysis. The characterization of the synthesized polymers were achieved by H-1 NMR, C-13 NMR and IR spectroscopy. The highest polymer yield was obtained from the decomposition of bis(4-bromo-2,6-dichlorophenoxo)(N,N,N',N'-tetramethylethylenediamine)copper(II) complex.

Synthesis of ferrocenyl pyrazoles by the reaction of (2-formyl-1-chlorovinyl)ferrocene with hydrazines
Zora, Metin (Elsevier BV, 2007-10-15)
Synthesis of ferrocenyl-substituted pyrazoles via the reaction between (2-formyl-1-chlorovinyl)ferrocene and hydrazine derivatives is described. Depending upon the substitution pattern of hydrazine, the reaction affords 1-alkyl/aryl-5-ferrocenylpyrazoles and/or 1-alkyl/ aryl-3-ferrocenylpyrazoles. The reaction appears to be general for a variety of hydrazine derivatives.
Synthesis of poly(dihalophenylene oxide)s by atom transfer radical rearrangement polymerization via Ce(IV)/Ce(III) complexes in solid state
Çelik, Güler (Informa UK Limited, 2006-01-01)
Poly(dihalophenylene oxide)s by solid-state thermal decomposition of (trihalophenolato) cerium complexes with either N-methyl imidazole or pyridine as neutral ligands were synthesized at different temperatures (80-250 degrees C) and different time intervals (3-48 h) via atom transfer rearrangement radical polymerization. The complexes were characterized by FT-IR, DSC, SEM, mass spectroscopy, magnetic susceptibility and elemental analyses. Structural analyses of polymers were performed by H-1- and C-13-NMR, ...
Synthesis of ferrocenyl pyrazoles by the reaction of 3-ferrocenylpropynal with hydrazinium salts
Zora, Metin; Odabasoglu, Mustafa; Bueyuekguengoer, Orhan; Turgut, Guenseli (Elsevier BV, 2008-01-01)
Synthesis of ferrocenyl-substituted pyrazoles via the reaction between 3-ferrocenylpropynal and hydrazinium salts is described. Depending upon the substitution pattern of hydrazine derivative, the reaction affords 1-alkyl/aryl-5-ferrocenylpyrazoles and/or 1-alkyl/aryl-3-ferrocenylpyrazoles. Structures of 5-ferrocenyl-1-phenyl-1H-pyrazole, 1-benzyl-5-ferrocenyl-1H-pyrazole and 2-(3-ferrocenylpyrazol-1-yl)ethanol were identified by X-ray crystallography.
Preparation of lead zirconate titanate (Pb(Zr0.52Ti0.48)O-3) by homogeneous precipitation and calcination
Oren, EE; Tas, AC (1998-05-06)
Aqueous solutions of lead chloride (PbCl2), zirconium oxychloride (ZrOCl2.8H(2)O) and titanium tetrachloride (TiCl4), in appropriate volumetric amounts, were used as the starting materials in the synthesis of phase-pure Pb(Zr0.52Ti0.48)O-3 powders. Preparation of the phase-pure PZT powders were achieved, in the presence of urea (CH4N2O), by the chemical powder synthesis route of homogeneous precipitation.
Effect of N-methyl imidazole and dimethyl pyrazole ligands on polymerization of di(2,4,6-trichlorophenolato)Cu(II)/Co(II) complexes in solid state
Kisakurek, D (Informa UK Limited, 2004-08-01)
Polymerization of 2,4,6-trichlorophenol (TCPH) was achieved through the thermal decomposition of the copper and cobalt complexes of TCPH with N-containing ligands [N-methyl imidazole (NMIz) and 3,5-dimethyl pyrazole (DMPz)). The structural analysis of the complexes was performed by using Fourier transform infrared (FTIR), differential scanning calorimetry (DSC), mass (MS), UV-VIS, diffuse reflectance (DRS) and electron spin resonance (ESR) spectroscopies, magnetic susceptibility balance and elemental analys...
