Abstract:
Keto esters 8, 4-arylcarbonyl-3-methoxycarbonyl-2-phenylfurans, potential precursors of the synthesis of furofuran lignans, were obtained from dimethyl 2-phenylfuran-3, 4-dicarboxylate 2. Diester 2 was selectively hydrolyzed to monoacid 6 followed by converting to its acid chloride 7. Friedel-Crafts acylation reactions of 7 with aromatic compounds afforded keto esters 8. The geometric structures of 8 and its precursors were elucidated and verified by NMR spectra.

Abstract:
While WCl6-Ph4Sn is a poor catalyst for the polymerization of 1-phenyl-butyne (PB) at room temperature, it effectively polymerizes PB in the presence of C60, giving high molecular weight polymers in high yields. The polymer is soluble in THF and chloroform and spectroscopic analysis reveals that C60 has copolymerized with PB. Thus, C60 plays dual roles of comonomer and cocatalyst in the acetylene polymerization. The copolymers strongly attenuate 532-nm laser pulses, whose limiting performance is superior to that of parent C60.

Abstract:
Metal (Me=Fe(Ⅲ), Mo(Ⅵ), Mn(Ⅱ), Co(Ⅱ), Ni(Ⅱ), Zn(Ⅱ) and Cu(Ⅱ)) 2-hydroxy-1-naphthaldehyde thiosemicarbazone complexes (MeHNT) were synthesized and used as mimic-enzyme catalysts to mimic the active group of horseradish peroxidase (HRP). The results showed that Fe-HNT, Mo-HNT are effective catalysts, which have similar catalytic activity as HRP. The sequence of catalytic activities of tested biomimic peroxidas is Mo-HNT> Fe-HNT> Zn-HNT> Ni-HNT> Mn-HNT. Among them, Fe-HNT is used as a mimic-enzyme catalyst in determination of ascorbic acid and glucose by coupling the catalytic reaction of glucose oxidase.

Abstract:
GC/MS has been used to identify gas phase products and intermediates formed during the gas phase photocatalytic oxidation of trichloroethylene (TCE) on TiO2 with low BET surface area. A new byproduct, oxalyl choloride (ClCOCOCl) was detected together with other byproducts such as COCl2, CHCl3, DCAC and C2HCl5. Firstly the method of perturbation on the reaction system was conducted. Very little amount of water was carried into the feed gas and subsequent changes were observed. The discussion based on the product distribution changes led to a postulated mechanism consisting of two stages.

Abstract:
A series of metal complexes were designed and synthesized and a novel binuclear magnesium complex has been selected, namely[Mg2(dien)Cl(OH2)2]Cl2·H2O (dien=diethylene-triamine), which can cleave the plasmid pBR322 DNA effectively in close to physiological condition without adding any external materials. Through biological and chemical methods, especially the comparative experiments, we find the interaction between the complex and DNA belongs to hydrolytic mechanism.

Abstract:
The glassy carbon substrates were bombarded with 5×1017 ions/cm2 of platinum. The surface composition of implanted electrode and concentration-depth profiles of various elements were measured by AES. The chemical state of Pt in glassy carbon electrode implanted with platinum (Pt/GC) was detected by X-ray Photoelectron Spectroscopy (XPS). The electro-oxidation of HCOOH and HCHO have been investigated on Pt/GC and smooth Pt electrodes. The results show that the platinum implanted into glassy carbon is much more active than the smooth platinum metal for electro-oxidation of HCOOH and HCHO.
