Authors: Chen Shi‐Fu , Cheng Xue‐Li 
Published: September 2010

AbstractThe photocatalytic reduction of dichromate using TiO2/beads as a photocatalyst was studied. The results showed hat 3.8 × 104 mol/dm3 of dichromate can be completely reduced into Cr3+ after illumination far 35 min with a 375 W medium pressure mercury lamp. The effects of factors such as the amount of TiO2/beads, initial concentration of dichromate, initial pH, nitrogen and oxygen atmosphere, and concentration of Fe3+ on the photocatalytic reduction of dichromate were investigated. A possible mechanism of the photocatalytic reaction was proposed. After illumination for 200 h, no significant loss of photocatalytic activity of TiO2/beads was observed.

Authors: Wang Dong 
Published: September 2010

AbstractThe effects of the chiral substituents attached to silicon on the stereoselectivity of the reactions of C‐centered chiral silicon compounds wm examined. The investigation was focused on the asymmetric C—C bond formation reaction of chiral allylsilanes and α‐silylallyl anions with aldehydes. The functionalities of the substituents on silicon can be manipulated to improve the stereoselectivities of the reactions remote from silicon atom.

Authors: Tu Chu‐Qiao , Liang Hong , Wang Guang‐Hui 
Published: September 2010

AbstractKinetic experiments were performed to study the effects of Pd2+ ion on the oxidation of 5,6‐dibromo‐2, 3‐dicyanohydroquinone catalyzed by Rhus vernicifera laccase under condition of pH 4.5 and 30 ± 0.1°C. The results showed that the mixed activation could be observed when Pd2 ion was at low concentrations. The competitive and non‐competitive activation constants were 9 × 10−‐6 and 2 × 10−‐6 mol/L, respectively. With the increase of Pd2+ ion concentration, the activation was gradually converted into mixed inhibition, and the competitive and non‐competitive inhibition constants were 6 × 10−‐6 and 32 × 10−‐6 mol/L, respectively.

AbstractFive oxovanadium(IV) dinuclear complexes described by the overall formula [(VO)2(IA)L2SO4, where IA repents the dianion of iodanilic acid and L denotes 2, 2′‐bipyridine (bpy); 4,4′‐dimethy12,2′‐bipyridine (Meo‐bpy); 1,10‐phenanthroline (phen); 4,7‐diphenyl‐l, 10‐phenanthroline (Ph2‐phen) and 5‐nitro‐1, 10‐phenanthroline (NO2‐phen), have been synthesized and characterized by elemental analyses, molar conductivity and roomtemperature magnetic moment measurements, IR and electronic spectral studies. It is proposed that these complexes have IA‐bridged structures and consist of two oxovanadium(IV) ions each in a square pyramidal environment. The complexes (VO)2(IA) (bpy)2]SO4, (1) and[(VO)2( IA) (phen)2 ]SO4 (2) were further characterized by variable temperature (4.2–300 K) magnetic susceptibility measurements and the observed data were fitted to the modified Bleaney‐Bowers equation by the least‐squares method, giving the exchange integral J = ‐ 2.15 m−1 for 1 and J = ‐ 9.88 cm−1 for 2. This result indicates that there is a weak antiferromagnetic spin‐exchange interaction between the two VO2+ ions within each molecule.

Published: September 2010

AbstractThe matrix elements of the correlation function between symmetric potential harmonics am simplified into the analytical summations of the grand angular momenta by dy using the recurrence and coupling relations of the potential harmonics. 'The correlation‐function potential‐harmonic and generalized‐Laguerre‐function method (CFPHGLF), recently developed by us, is applied to the S states of the helium‐like systems for Z = 2 to 9. The results exhibit good convergence with the bases in tern of both the angular and radial directions. The final eigen‐energies agree excellently with the best s‐limits of the variational configuration interaction (CI) method for the involved low‐lying S states. The accuracy of the potential harmonic (PH) expansion scheme is discussed relative to the exact Hylleraas CI results (HCI), and Hartree‐Fock results. Moreover, suggestion is given for the future improvement of the PH scheme.

Authors: Gao‐Sheng Chu, , Jia‐Fu Chen, , Zhi‐Cheng Zhang, , Si‐De Yao, 
Published: September 2010

AbstractThe interactions of oxidative radicals (Br2−‐, HO− etc.) with N‐phosphoryl dipeptide derivatives (NDM‐TrpOMe and NDT‐MetOMe) have been investigated by using pulse radiolysis at different pH values. It has been found that Br2−‐ and HO− radicals oxidize the Met‐site and Trp‐site in the dipeptide derivatives via formation of the three‐electron‐bonded intermediate and indolyl radical simultaneously. Then the intramolecular electron transfer along the peptide backbone occurs. The rate constants of electron transfer, k, have been determined and the reaction mechanism has been deduced.

AbstractTwo series of mixed oxides, GIAlM and MgAlM (M= G, Mn, Fe, Co, Ni, Cu), were prepared by calcining their corresponding hydrotalcite‐like compounds (HTLc). The ratio of Mg: Al: M (or Co: Al: M) was 3:1:1. The catalytic activity of all samples for the reaction of NO + CO was investigated. The results showed that the activity of CoAlM was much higher than that of MgAlM. The structure and the property of redox were characterized by XRD and H2‐TPR. The results indicated that only MgO phase was observed after calcining MgAlM hydrotalcites, and the transition metals became more stable. The spinel‐like phase appeared in all of CoAlM samples after the calcination, and the transition metals were changed to be more active, and easily reduced. The activities of three series of mixed oxides CoAlCu obtained from different preparation methods, Different ratio of Co: Al: Cu and at different calcination temperatures. were studied in detail for proposing the mechanism of reaction. The ability of adsorption of NO and CO were investigated respectively for supporting the mechanism.

AbstractA partially substituted β‐cyclodextrin chiral stationary phase was prepared by the reaction of phenyl isocyanate. The enantiomers of a series of O,O‐diethyl(p‐methylbenzenesulfonamido)‐aryl(or alkyl)‐methylphosphonates were studied on the prepared phenyl carbamate derivative β‐cyclodextrin bonded phase and a commercial (S)‐(+)‐1–(1‐naphthyl) ethylcarbamate derivative β‐cyclodextrin bonded phase on normal phase chromatographic condition. Results show that the prepared phenyl carbamate derivative β‐cyclodextrin bonded phase has better enantiomeric selectivity to the series of compounds. A chiral recognition mechanism was suggested for the separation of these novel organic phosphorus enantiomers.
Design, synthesis and bioactivity of novel herbicides targeted ALS (VII): Quantitative structure‐activity relationships of herbicidal sulfonylureas
Authors: Guang‐Fu Yang, , Hua‐Zheng Yang, 
Published: September 2010

AbstractThe quantitative relationship between the structures of 20 sulfonylureas and their herbicidal activities against rape was analyzed using physicochemical parameters and regression analysis. The results showed that the electronic properties of the molecules are the dominant factor to the activity and there is apparently an optimum electronic property (Σs̀ or pKa) for the molecules to fit the receptor. Combined with the preview QSAR results for herbicidal triazolopyrimidine‐2‐sulfonamides, we can conclude that the structure‐activity relationships of these two sets of compounds are identical, which suggested that these two sets of compounds acted on the same target site.

Published: September 2010

AbstractThe complete amino acid sequence of β‐momorcharin, a ribosome‐inactivating protein from the seeds of Momordica charantia Linn (Cucurbitaceae) has been determined. This has been done by the sequence analysis of peptides obtained by enzymatic digestion with trypsin, chymotrypsin and S.aureus V8 protease, as well as by chemical cleavage with BNPS‐skatole. The protein consists of 249 amino acid residues containing one asparagine ‐ linked sugar group attached to the site of Asn 51 and has a calculated relative molecular mass of 28,452 Da without addition of the carbohydrate. Comparison of this sequence with those of trichosanthin and other ribosome‐inactivating proteins from different species of plants shows a significant homology with each other. Regarding the similarity of their biological properties, an active domain of these proteins has been predicted here.

Published: September 2010

AbstractThe kinetic model of induced codeposition of nickel‐molybdenum alloys from ammonium citrate solution was studied on rotating disk electrodes to predict the behavior of the electrode‐position. The molybdate (MoO42−) could be firstly electro‐chemically reduced to MoO2, and subsequently undergoes a chemical reduction with atomic hydrogen previously adsorbed on the inducing metal nickel to form molybdenum in alloys. The kinetic equations were derived, and the kinetic parameters were obtained from a comparison of experimental results and the kinetic equations. The electrochemical rate constants for discharge of nickel, molybdenum and water could been expressed as k1,(E) = 1.23 × 10−9 CNexp( ‐ 0.198 FE/RT) mol/(dm2 · s), k2 (E) = 3.28 × 10−10 CMoexp ( ‐ 0.208FE/ RT) mol/(dm2 · s) and k3(E) = 1.27 × 10−6 exp ( ‐0.062FE/ RT) mol/(dm2 · s), where CN and CMo, are the concentrations of the nickel ion and molybdate, respectively, and E is the applied potential vs. saturated calomel electrode (SCE). The codeposition process could be well simulated by this model.

Published: September 2010

AbstractThe binding of Mn(II) to human serum albumin (HSA) or bovine serum albumin (BSA) has been studied by equilibrium dialysis at physiological pH (7.43). The Scatchard analysis indicates that there are 1.8 and 1.9 strong binding sites of Mn(II) in HSA and BSA, respectively. The successive stability constants which are reported for the first time are obtained by non‐linear least‐squares methods fitting Bjerrum formula. For both Mn(II)‐HSA and Mn(II)‐BSA systems, the order of magnitude of K1 was found to be 104. The analyses of Hill plots and free energy coupling show that the positive cooperative effect was found in bom Mh(II)‐HSA and Mn(II)‐BSA systems. The results of Mn (II) competing with Cu (II) Zn(II), Cd(II) or Ca(II) to bind to HSA or BSA further support the conjecture that there are two strong binding sites of Mn(II) in both HSA and BSA. One is most probably located at the tripeptide segment of N‐terminal sequence of HSA and BSA molecules involving four groups composed of nitrogen atoms, and the fifth coordination atom is the carboxyl oxygen of Asp1. The coordinated atoms of the other are most probably almost all oxygen atoms.

AbstractThe structure of trans‐[Pd‐(dtco‐3‐OH)2] (ClO4)2·2DMSO, in which dtco‐3‐OH is dithiacyclooctan‐3‐ol and DMSO is dimethyl sulfoxide, was determined by X‐ray crystallographic analysis. The crystal data: space group p1, a = 0.7077(2) nm, b = 1.0788(1) nm, c = 1.1111(1) nm, α = 67.710(8)°, β = 73.59(2)°,γ = 85.39(2)°, R1 = 0.0368 and Rw = 0.0998. The palladium (II) is coordinated by four sulfur atoms with a regular square planar configuration. The Pd—S distances are 0.2314(1) and 0.2317(1) nm, respectively. Both dtco‐3‐OH ligands are in the boat‐chair configuration and two hydroxyl groups are on the opposite sites of the PdS4 coordination plane and are towards Pd(II). The Pd—O distance is 0. 285 nm, indicating a weak interaction between them. A typical hydrogen bond between the hydroxyl group of dtco‐3‐OH ligand and DMSO was observed in the crystal structure. An aqueous solution prepared with the crystals of the complex was used for the investigation of electrospray mass spectrometry (ESMS). Besides trans‐[ Pd (dtco‐3‐OH)2]2+ . 2DMSO observed, in the full scan spectrum of ESMS, all relative species of it, which were probably produced during electrospray ionization process, were also detected. From these experiments, it reveals that ESMS is a powerful tool for studying noncovalent interaction present in solution between inorganic complexes and solvents.

Published: September 2010

AbstractCalix[4] (aza) crowns containing amide groups 3a—d were synthesized by the reactions of calix[4]arene (la) or p‐tert‐butylcalix[4]arene (1b) with N, N′‐ethylenebis(2‐chloroacetamide) (2a) or N, N′‐ 1,2‐ethylenebis (2‐chloroacetamide) (2b) by one step procedure in yields of 85—‐90%. Calix[4]‐(aza) crowns 4a—b could be obtained by the reduction of 3a—b with LiAlH4 in yields of 51 and 67%, respectively. The nitration of 3a or 3c afforded new chromogenic calix[4]arenes 5a bearing two nitrophenol moieties and 5c bearing one nitro‐phenol and one quinone moiety, respectively. The ipso‐nitration's of 3b and 3d were also studied. Both gave the products containing one nitro phenol and one quinine moiety. Moreover, a very interesting calix[4]arene derivative 5d containing one cyclohexadienone moiety was also separated as the main product when 3d was ipso‐nitrated.

AbstractEmission quenching of [Ru(bpy)2(4,4′‐dcbpy) ] (PF6)2 (1) by benzenamine,4‐[2‐[5‐[4‐[4‐dimethylamino]phenyl]‐4,5‐dihydro‐l‐phenyl‐1H‐pyrazol‐3‐yl]‐ethenyl]‐N, N‐dimethyl (2) or 1,5‐diphenyl‐3–(2‐phenothiazine)‐2‐pyrazoline (3) was observed. Measurements of the emission decay of 1 before and after addition of 2 or 3 by single photon counting technique confirmed the observations. The emission quenching of 1 by 2 or 3 was submitted to Stern‐Volmer equation. It was calculated that the quenching rate constants (Kq) are 5.5×109 (mol/L)−1s−1 for 2 and 4.0×109 (mol/L)−1 for 3, respectively. These results indicated a character of dynamic quenching process. The singlet‐state of 2 or 3 was also quenched by 1. The quenching behaviors did not conform to the Stern‐Volmer equation and involved both static and dynamic quenching processes. The apparent quenching rate constant (kapp) was calculated to be 3×109 (mol/L)−1 for the interaction of excited 2 with 1, and 1.2×109 (mol/L)−1 for that of excited 3 with 1.
