In this paper,α,β–Unsaturated N– benzenesulfonyl imine was treated with 1.1 eq methyllithium to afford 1,2–addition adduct as a sole product. However, when α,β–Unsaturated N– benzenesulfonyl imine was treated with 2 eq MeLi, 1,2–addition product, benzenesulfonamide derivative and 2H–1,2– benzothiazine 1,1–dioxide derivatives were isolated. More details will be discussed in this issue on page 573–576.

α,β-Unsaturated N-benzenesulfonyl imine 1 was treated with 1.1 eq methyllithium to afford 1,2-addition adduct as a sole product. However, when compound 1 was treated with 2 eq MeLi, 1,2-addition product, benzenesulfonamide derivative 3 and 2H-1,2-benzothiazine 1,1-dioxide derivatives 4 and 5 were isolated.

The concentration of NaOH solution had an important effect on the ZnO-graphene composite. With increasing the concentration of NaOH solution, the defects of the composite firstly increased, and then decreased, which affected the change of spectral characteristics. The structure and interface electronic interaction between ZnO and graphene will be useful for designing ZnO-graphene based photoelectrical devices.

The unimolecular reactions of HFCO and DFCO have been studied by RRKM theory. The barriers are calculated at MP2/6-311++G(3df,3pd) level. The harmonic and anharmonic rate constants of the HFCO and DFCO decompositions have been calculated.

Hydrogen is a superb energy carrier. The characterization of CH₄ decomposition using MgO, TiO₂ and Al₂O₃ catalysts revealed the formation of multi-walled nanotubes. Methane conversion increased and catalyst surface areas decreased as the % Fe loading was increased. 60%Fe/Al₂O₃ gave the highest catalytic activity of 69% CH₄ conversion.

The fibres were prepared by combining surfactant N, N-dimethylferrocenylmethyl hexadecyl-ammonium bromide (Fc16AB) and fluorescent dye methyl orange (MO) using ion self-assembly techniques. The concentration of Fc16AB and MO have great effects on the morphology of obtained microfibers.

Zinc zirconium phosphate was prepared and used as an efficient catalyst for the selective oxidation of various alcohols to the corresponding aldehydes and ketones, in good yields and with excellent selectivities.

The activity of Pd(II)-Schiff base complex molecules grafted on the surface of Fe₃O₄@SiO₂ particles were investigated in the palladium-catalyzed coupling reactions of aryl halides with alkenes (Mizoroki-Heck reaction) and phenylboronic acids (Suzuki-Miyaura reaction) in the absence of phosphorous ligands.

A series of novel­ N-aryl-4-(tert-butyl)-5-(1H-1,2,4-triazol-1-yl)thiazol-2-amine were synthesized. H₂O₂-NaBr Brominating system was used in the synthesis of the key intermediate in a mild condition. All of the target compounds were tested for their cytotoxicity against two different human cancer cell lines. Some of the title compounds showed moderate to strong cytotoxic activities.

The electrocatalytic oxidation of NADH was studied on nanoTiO₂ modified sol-gel electrode, using cyclic voltammetry, chronoamperometry and differential pulse voltammetry as diagnostic techniques. TiO₂ nanoparticles on sol-gel network catalyze the oxidation of NADH in the absence of any electron transfer mediators. This method was used for determination of NADH in cucumber cotyledons using DPV with detection limit of 0.35 μM.

A Mg₂Al-Cl layered double hydroxide modified carbon ionic liquid electrode was prepared and further used for the sensitive electrochemical detection of rutin.

HPLC chromatograms of the chiral drugs on the optimum chromatographic condition, a: mandelic acid, α = 1.14; b: 2-chloromandelic acid, α = 1.29; c: ketoprofen, α = 1.17.

A simple but sensitive sensor, ERGO/GCE, was fabricated by coating of GO solution on GCE surface and then electrochemically reduced to ERGO by successive CV scanning. As a voltammetric sensor, ERGO/GCE not only could be obtained simply, but also showed more sensitive response for ESC. Based on this property, a new voltammetric method for determination of ESC was proposed. The advantages of present method were high sensitivity, wider linear range, good accuracy and precision.
