	Abstract:A series of heterobimetallic dianionic guanidinate complexes of lanthanide and lithium, [Li(THF)(DME)]3Ln[μ-η2η1(iPrN)2C(NC6H4p-R)]3 [R = Cl, Ln = Nd (I), Y (II), La (III); R = H, Ln = Nd (IV)] were synthesized and fully characterized. These complexes were found to be highly efficient precatalysts for the addition of various primary and secondary amines, and aromatic and aliphatic diamines to carbodiimides to the corresponding monoguanidine and biguanidine derivatives under mild condition (at 25-40 oC), which provides an efficient way for the synthesis of biguanidines compounds. The activity depends on the central metals and ligands: La > Nd > Y for metals and [(iPrN)2C(NC6H4p-Cl)]2- > [(iPrN)2C(NC6H5)]2- for ligands around lanthanide ion were observed.

	Abstract:Two stilbazolium derivatives with different counter-anion (Br- and OH-) have been designed and synthesized. Different counter-anion causes different aggregation properties. The reason of the difference was investigate through concentration- and temperature-dependent 1H NMR and IR spectra. When the counter-anion is OH-, the stilbazolium derivative exhibit pronounced aggregation properties. The SEM images of xerogels show the characteristic gelation morphologies of 3D fibrous network structures. X-ray diffraction (XRD), and fluorescence spectroscopy studies have been carried out and provide more information to define the molecular packing model in gelation states. Finally, the acid sensing abilities of the xerogel film was study.

	3. A single component organic ferroelectric compound with helical hydrogen bond chains: crystal structure, ferroelectric and dielectric properties
	Liu Xu,Yu Weihua,Liu Jianlan,Ren Xiaoming

	Abstract:An organic compound, 2-amino-4-phenylthiazole, crystallize in the polar space group P41; the neighboring molecules form a helical H-bonding chain along the crystallographic c-axis direction, and there are weak van der Waals forces between the adjacent H-bonding chains in the crystal. This compound shows ferroelectricity which is confirmed by the P-E hysteresis loop and dielectric spectroscopy. The theoretical analyses further revealed that the switch between two stable polarization states ?P and +P of the ferroelectricity under an external electric field can be easily achieved by the relative rotation of the thiazolyl and phenyl rings around C-C single bond of 2-amino-4-phenylthiazole.

	Abstract:C70 clusters have been deposited as nanostructured films on optically transparent electrode (OTE) surfaces using an electrophoretic approach. Upon electrodeposition of platinum particles, these nanostructured C70 films show notable activity toward methanol oxidation. The dependence of methanol oxidation on the amount of Pt and C70 in a half-cell reaction demonstrates the role of [70]fullerene nanocluster as new form of carbon support. The C70 films have a better activity for methanol oxidation than C60 films have.

	Abstract:A flexible array of C60-polymethyl methacrylate (PMMA) composite nanotubes and nanowires, having diameters in the range of 90-180 nm and length up to 30 microns, was fabricated by a controllable technique and characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), ultraviolet (UV) and infrared (IR) spectroscopy. The ability to prepare the fullerene composite nanowire and nanotube arrays with controlled structures represents an important step toward the development of chemical sensors, catalyst, optical devices and nanoscale electronic devices based on fullerenes.

	Abstract:Theoretical calculations were used to explore the complete reaction mechanism of nickel-catalyzed [3+2+2] cocyclization of ethyl cyclopropylideneacetate and phenylacetylene. The lowest energy pathway is made of a series of ring-opening and closing with a C-C bond formation step as the rate-determining step of the overall reaction. The energy barrier with ZPE for this step is 16.9 kcal/mol and in agreement with the reported reaction conditions.

	Abstract:Organotin derivatives as well as pyrazole and their derivatives play crucial roles as the active moieties in varieties of agrochemicals. Along with the increasing interest in use of sulfur- or nitrogen-functionalized carboxylic acids to yield organotin carboxylates with various and fascinating structures and different bioactivities, these features encourage the exploitation of the biological activity of organotin carboxylates containing pyrazole. In this paper, a series of organotin 1-phenyl-3,5- dimethylpyrazole-4-carboxylates and 1-(2-pyridyl)-3,5-dimethylpyrazole-4-carboxylates have been obtained and characterized by IR, NMR (1H, 13C and 119Sn) and elemental analysis. The structure of triethyltin 1-phenyl-3,5-dimethylpyrazole-4-carboxylate has been further confirmed by X-ray diffraction crystallography. This complex crystallizes with a molecule of water and forms an infinite 2D network through intermolecular O-H…O and O-H…N hydrogen bonds. Fungicide screening indicates that all complexes display good growth inhibition against Alternaria solani, Cercospora arachidicola, Gibberella zeae, Physalospora piricola and Botrytis cinerea. Moreover, high growth inhibition percentage at 50 μg/ml was observed in vitro in case of triorganotin 1-phenyl-3,5-dimethylpyrazole-4-carboxylates and 1-(2-pyridyl)-3,5-dimethylpyrazole-4-carboxylates. The corresponding EC50 of these highly active triorganotin carboxylates have been detected. The value of EC50 of triethyltin 1-(2-pyridyl)-3,5-dimethylpyrazole-4-carboxylate is only 0.06 μg/ml against Physalospora piricola and 0.14 μg/ml against Gibberella zeae, respectively.

	Abstract:An enantioselective Biginelli reaction has been developed by using a bifunctional primary amine-thiourea-TfOH (BPAToTfOH) as a chiral phase-transfer catalyst and t-BuNH2oTFA as an additive in saturated brine at room temperature. The corresponding dihydropyrimidines were obtained in moderate-to-good yields with up to 99% ee under mild conditions. A plausible transition state has been proposed to explain the origin of the activation and the asymmetric induction.

	Abstract:A convenient method has been developed for the diastereoselective synthesis of diisopropyl (R,R)-2-hydroxy-3-{(((R/S)-1-diethylphosphorylamido-1-arylmethyl) hydroxyphosphinyl)oxy}succin ate through Mannich-type reactions. The diastereoselectivity of the reaction using chiral reactant was investigated. The chiral 2-chloro-(4R,5R)-dicarboisopropoxy-1,3,2-dioxaphospholane 3 was found to be a good stereoselective phosphonylating agent towards this reaction.
