摘要：
This paper deals with the synthesis of a new hybrid meso-tetraarylporphyrin-cardanol with the cardanol bearing an unsaturated chain. Cardanol is a renewable, natural, widely available and relatively low-cost material obtained as a by-product of the cashew industry which provides cashew kernels for edible use. The unsaturation in the chain in the new hybrid meso-tetraaryiporphyrin-cardanol leads to chemical and physico-chemical properties which are different from the saturated derivatives. The unsaturation also allows preparation of the corresponding epoxy compounds as well as self-metathesis derivatives. Copyright (c) 2006 Society of Porphyrins & Phthalocyanines.

摘要：
The reaction of 5-methyl-2-phenyl-2H-1,2,4-triazol-3(4H)-one, benzaldehyde and malononitrile in ethanol in the presence of triethylamine produced the title compound, C10H8N2, rather than the anticipated polysubstituted 2,6-dicyanoaniline. The plane defined by the phenyl ipso-C atom, the methylene C atom and the central C atom of the malononitrile group is roughly orthogonal to the benzene ring plane [dihedral angle = 81.6 (2)°]; one of the nitrile groups of the malononitrile almost lies in this plane [corresponding C(Ph)-CH2-C-CN torsion angle = 176.06 (17)°]. © 2006 International Union of Crystallography All rights reserved.

摘要：
A series of nickel complexes with β-ketoamine ligands based on pyrazolone derivatives were synthesized by condensing pyrazolone with aniline, 2-chloroaniline or naphthylamine and then reacting the produced β-ketoamine with nickel halide. The solid-state structures of these three complexes were determined by single-crystal X-ray diffraction. The bis(β-ketoamine)nickel complexes are all air-stable and can act as highly active catalyst precursors for styrene polymerization with activation of methylaluminoxane under mild reaction conditions. The activity of the catalyst for styrene polymerization is as high as 2.10 × 105 g polymer/mol Ni h. Both steric and electronic effects were found to be important and influential for catalytic activity. Copyright © 2005 John Wiley & Sons, Ltd.

摘要：
The degradation of imazapyr in four soils was investigated under laboratory aerobic and anaerobic conditions. Under aerobic conditions, imazapyr degraded faster in yellow-red soil than in other soils, and its persistence decreased depending on soil pH in the order coastal soil (pH 8.8) >silt-loamy paddy soil (pH 7.9) >fluvio-marine yellow loamy soil (pH 7.1) >Yellow-red soil (pH 5.3). However, soil pH did not affect imazapyr degradation under anaerobic conditions. The half-lives of imazapyr in soils under aerobic conditions were in the range of 26-44 days estimated by the first-order kinetics model, while 3-10 days calculated by two-stage model under anaerobic conditions. The preceding results demonstrated that anaerobic conditions contributed to imazapyr disappearance in soils. Based on the spectral data of APCI-MS, <sup>1</sup>H NMR and IR, structures of the following metabolites: 2,3-pyridinedicarboxamide, 2,3-pyridinedicarboxylic anhydride and 2,3-pyridinedicarboximide for aerobic treatments;2,3-pyridinedicarboxylic anhydride and 2-(4-hydroxy-5-oxo-2- imdazolin-2-yl) nicotinic acid for anaerobic treatments, were identified. Degradation mechanism under the different conditions was also discussed. ©2006 Taylor &Francis.

The crystal belongs to monoclinic, space group P21/c with a = 14.8442(11), b = 11.5131(8), c = 17.2010(13) Å, β = 113.7250(10)°, V = 2691.3(3) Å3, Z = 4, Dc = 1.440 g/cm3, 5 = 1.094, μ = 0.547 mm-1, F(000) = 1200, the final R = 0.0571 and wR = 0.1458. X-ray analysis reveals that the title compound combines with a molecule of dichloromethane by an intramolecular hydrogen bond. The thienopyridine ring is almost coplanar, and the dihedral angle between the thiophene plane and the pyridine plane is 0.6°.

The title complex, [CaZn(C<inf>3</inf>H<inf>2</inf>O<inf>4</inf>) <inf>2</inf>(H<inf>2</inf>O)<inf>4</inf>]<inf>n</inf>, is a two-dimensional polymer and consists of CaO<inf>8</inf> and ZnO<inf>6</inf> polyhedra linked together by malonate ligands. The Ca<sup>II</sup> cation, lying on a twofold axis, is coordinated by two water molecules and six malonate O atoms. The Zn<sup>II</sup> cation, which lies on an inversion center in an octahedral environment, is coordinated by four malonate O atoms in an equatorial arrangement and two water molecules in axial positions. The Zn - O and Ca - O bond lengths are in the ranges 2.0445(12)-2.1346(16) and 2.3831(13)-2.6630(13), respectively. The structure comprises alternating layers along the [101] plane, the shortest Zn&mellip;Zn distance being 6.8172(8). The whole three-dimensional structure is maintained and stabilized by the presence of hydrogen bonds. ©2006 International Union of Crystallography.

摘要：
A method for determination of L-dopa by the adsorption stripping voltammetry (ASV) using a multiwalled carbon nanotubes (MWNTs)-Nafion modified glassy carbon electrode (GMGCE) was proposed. This chemically modified electrode (CME) shows a better stability. A sensitive oxidation peak was observed and the anodic peak potential is ca. 0.374V (vs. SCE). The influences of various experimental parameters on the current peak were completely studied. Under the optimized condition, the method has been applied to the determination of L-dopa in samples. There is a good linear relationship between the peak current (i p) and L-dopa concentration in the range of 3.5 × 10 -7 ∼ 1.5 × 10-5 mol/L, with the limit of detection 5.0 × 10-8 mol/L.

摘要：
A capillary electrophoresis coupling with indirect chemiluminescence detection method for the simultaneous determination of benserazide and levodopa has been developed. The detection interface was improved to simplify the capillary electrophoresis-chemiluminescence (CE-CL) system and the features of this improved interface were illustrated in this paper. The CE-CL conditions for the simultaneous determination of benserazide and levodopa were optimized. Under the optimal conditions, the CL intensity was linear with concentrations of levodopa in the range of 1.0 to 100.0 μg ml<sup>-1</sup>, and benserazide in the range of 10.0 to 1000 μg ml<sup>-1</sup>, respectively. The detection limits (S/N = 3) in turn were 1.85 μg ml<sup>-1</sup> for BS and 0.12 μg ml<sup>-1</sup> for L-dopa with relative standard deviations of less than 3%. The proposed method has been successfully applied to the determination of benserazide and levodopa in medopar tablets and spiked urine samples, demonstrating the feasibility and reliability of the proposed method. ©2006 Elsevier B.V.
