	Abstract:A substrate scopes of cyclopropanation has been expanded with trifluoroethylamine hydrochloride catalyzed by TPFPPFeCl under a user-friendly condition. Trifluoromethyl-substituted cyclopropanes were generated with high diastereoselectivity and yield, employing styrene derivatives and other heterocyclic alkene as substrates. Moreover, mechanism study shows TPFPP(NO) is the most important reaction intermediate which has not been reported in other metalloporphyrin-catalyzed cyclopropanation reactions.

	Abstract:In this study, four kinds of ionic liquids (ILs) with different carbon chain lengths based on 8-Hydroxyquinoline have been synthesized and used as the corrosion inhibitions for copper in 0.5 M sulfuric acid solution. The data of impedance spectroscopy, polarization curves and scanning electron microscope (SEM) show a positive correlation relationship between inhibitor concentration and inhibition efficiency. Besides, the introduction of alkyl groups in the molecular structure contributes to slow down the corrosion of copper, and inhibition efficiency rises firstly and then declines with the incremental alkyl chain length. The theoretical calculation result is consistent with the abovementioned experiments results. Furthermore, the adsorption of the investigated inhibitors on the copper surface obeys the Langmuir adsorption isotherm.

	Abstract:In this paper, on the basis of the special activity of natural rosin derivatives and the good asymmetric induction activity of squaramide organic catalysts, a novel dehydroabietylamine-cinchonine-squaramide catalyst has been developed for asymmetric Michael addition of 2,4-pentanedione to nitroalkenes. It found that with using 5 mol% dehydroabietylamine-cinchonine-squaramide catalyst , the reaction of 2,4-pentanedione to nitroalkenes could act effectively, and a series of nitroalkene derivatives possessing optical activity were afforded with high reaction yields and excellent enantioselectivities (up to 99% yield, 89% ee).

	Abstract:A new approach towards 2-phosponylated indoles was herein reported. The oxidative methodology took place selectively in a dehydrogenative coupling manner, furnishing the 2-substituted indoles as the exclusive product in moderate to good yields. The yield was depressed by the addition of TEMPO (2,2,6,6-tetramethyl piperidine 1-oxide), indicating the reaction proceed through the radical pathway.

	5. A New Supramolecular Fluorescence Probe for Distinguishing waste oil by Determination of Dodecylbenzenesulfonic Anion
	Chen Genting,Huang Huarong
	Chemistry 06 April 2013
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Dodecylbenzenesulfonic anion (DBSA) is often found in waste oil, which indicates the possibility of distinguishing waste oil by determination of DBSA. For this purpose, a new supramolecular fluorescence sensor based on tris(thiourea) and 1,8-naphthanlimide derivative moieties was designed and synthesized. Fluorescence spectra of the sensor with addition of dodecylbenzenesulfonic anion showed evident fluorescence enhancement due to their PET quenching system triggered by host-guest hydrogen-bonding interaction, which demonstrated that a new method to distinguish waste oil with the tripodal sensor via fluorescence spectroscopy can be established. Through a series of experiments, this method was found to be simple, effective and practicable.

	Abstract:Cis/trans 1,2-dicyanoethylenes bearing tetrathiafulvalene units linked by ethylenedithio spacer were prepared. The cis isomer was converted to eight tetrathiafulvalene unit substituted magnesium porphyrazine upon a metal-templated cyclotetramerization with magnesium propoxide in propanol. The dicyanoethylenes and target compound were characterized by EA, NMR, and MALDI-TOF mass and photophysical and Electrochemical propeties were discussed.

	7. An efficient and recyclable water-soluble palladacycle precatalyst for Suzuki coupling in aqueous solvents under aerial conditions

	Abstract:Several water-soluble palladacycles were prepared as air-stable solid from the imine ligands bearing sulfonic group on N-phenyl group. The palladacycles with a six-membered ring gave high catalytic efficiency for the Suzuki coupling of aryl bromides and an activated aryl chlorides in aqueous solvent under mild conditions. The palladacycle 1 can be used for five reaction cycles in high conversions for the Suzuki coupling of 4-bromoanisole at reflux temperature in neat water. TEM analysis suggests a catalytic mechanism of recyclable palladium nanoparticles for the Suzuki coupling. The surfactant-protected palladium nanoparticles gave lower yields of the coupling product than those generated from palladacycle in situ due to the capping of free sites of metallic species.

	Abstract:A novel and effective protocol for the synthesis of 2-substituted-3-halo-1H-indoles by PdX2/CuX2-catalyzed annulations of 2-ethynylbenzenamines has been developed. In the presence of PdX2 and CuX2, the annulation reactions of a variety of 2-ethynylbenzenamines were conducted in moderate to good yields. It is noteworthy that only N-acetyl protected 2-ethynylbenzenamines can undergo the reaction successfully.
