	Abstract:Reaction of anhydrous LnCl3 (Ln = Y, Nd, Sm and Yb) with enol-functionalized imidazolium salt H2LBr (L= 4-OMe-C6H4COCH{C(NCHCHNiPr)}) and NaN(TMS)2 at a molar ratio of 1:4:1 in THF at room temperature afforded the corresponding novel enol-functionalized N-heterocyclic carbene (NHC) lanthanide amides L2LnN(TMS)2 (Ln = Y (1), Nd (2), Sm (3), Yb (4)) in 37-40% yields. Molecular structures of complexes 1-4 were determined by X-ray structure analyses. All these complexes adopt monomeric structures where each 5-coordinated metal is coordinated by two NHC ligands and one amido group.in distorted trigonal bipyramid geometry. These complexes, especially the Yb complex 4 were found to be highly active precatalysts for the catalytic addition of amines to carbodiimides giving guanidines, Complex 4 shows good functional group tolerance and a wide scope of amines including primary and secondary cyclic amines.

	Abstract:A novel tris(dibenzoylmethanato)[5-(2-(4-tert-butylbenzenyl)-5-benzenyl-1,3,4-oxadiazole -4’)-1,10-phenanthroline]europium(III) [Eu(DBM)3(BuOXD-Phen)] containing an electron-transport- ing oxadiazole functionalized phenanthroline, was synthesized and characterized. Its UV-vis absorption and photoluminescence, as well as the electroluminescence in polymer light-emitting devices (PLEDs) were investigated. The double-layer PLEDs with a configuration of ITO/PEDOT:PSS (50 nm)/PVK (40 nm)/PFO:PBD (30%):Eu(DBM)3(BuOXDPhen) (1-8 wt %) (80 nm)/Ba (4 nm)/Al (150 nm) were fabricated. Saturated red europium(III) ion emission, based on the 5D0→7F2 transition, is centered at a wavelength of 614 nm with a full width at half maximum (FWHM) of 10 nm. The highest external quantum efficiency of 1.26% photons per electron at current density of 0.63 mA/cm2, with maximum brightness of 61.2 cd/m2 at 144.7 mA/cm2, was achieved in the double-layer PLEDs. The results indicate that an introduction of oxadiazole groups into phenanthroline ligand can improve the performance of its europium complex doped PLEDs.

	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.

	Abstract:hree novel tetrathiafluvalene-annulated metalloporphyrazine dyes with electron- withdrawing pentoxycarbonyl groups at periphery were synthesized via a cyclotetramerization of dipentyl 6,7-dicyanotetrathiafulvalen-2,3-dicarboxylate in the presence of corresponding metal salts (Zn(OAc)2•2H2O, Cu(OAc)2•2H2O, and NiCl2) in pentanol and the structures were fully characterized by 1H-NMR, FT-IR, UV-vis, MULDI-TOF mass spectra and elemental analysis. The newly synthesized macrocyclic dyes are sufficiently air-stable for the purification process, where the electron-withdrawing substituents reduced the propensity to form the radical cation of tetrathiafulvalene groups . Their solution electrochemical data show one reductive and three oxidative processes within -2000 mV to +2200 mV potential window. Four couples can be assigned to Pz-2/Pz-3 (I), TTF+•/TTF (II), TTF+2/ TTF+• (III), and Pz-1/Pz-2 (IV).

	Abstract:The PtCl2-catalyzed reactions between indoles and ethyl propiolate gave rise to mono and double addition products. The composition of the products was largely influenced by the substituents on the indoles as well as the amount of ethyl propiolate used. o-Alkynylanilines reacted with ethyl propiolate and dimethyl acetylenedicarboxylate under the catalysis of PtCl2 to generate the corresponding 2,3-disubstituted indoles. The reaction proceeded following a sequential cyclization/intermolecular addition pathway.

	Abstract:A new chiral bifunctional catalyst had been developed for the asymmetric cyanosilylation of aldehydes. The complex of 1d with Ti(OiPr)4 could efficiently promote the addition of trimethylsilylcyanide to aldehydes in high yields (up to 99%) with up to 76% ee. Based on the preliminary investigation, a possible catalytic mechanism via dual activation has been proposed to explain the origin of the activation and asymmetric inductivity.

	Abstract:The asymmetric ring-opening of monosubstituted epoxides with dithiophosphorus acids catalyzed by a (salen)Ti(IV) complex formed in situ from the reaction of Ti(OPr-i)4 and the chiral salen ligand derived from (1R,2R)-(+)-diaminocyclohexane and (R)-2,2’-diamino-1,1’- binaphthalene was realized. The resulting products were obtained with moderate enantioselectivity (up to 59% ee). High regioselectivity was observed for the alkyl substituted epoxides, whereas poor regioselectivity was obtained for the aryl substituted epoxides.
