New solid complex of the antimony trichloride and dioxane was obtained th rough a reaction of the dioxane and the absolute methanol solution of the antimony trichloride.The formula of the complex is[SbCl3·{(CH2)4O2}1.5].The crystal structure of the complex belongs to cubic system,space group I-43d,a=17.1417(5)Å,Z =16.The trivalent antimony ion n ot only bonds directly to three chlorine anions,but also is coordinated by three oxygen atoms of th e dioxane molecules.Two oxygen atoms in a dioxane molecule will coordinate to different antimony ions,respectively. 相似文献

A facile, InCl3 and/or DABCO mediated 1, 3-dipolar cycloaddition of ethyl diazoacetate (EDA) with various activated olefins under solvent-free conditions at ambient temperature to afford 3, 5-disubstituted pyrazolines and pyrazoles in moderate to good yields is reported. 相似文献

A series of dibenzo[a,h]anthracene derivatives were synthesized through a straightforward, one-pot protocol based on a three-component reaction with 2-hydroxy-1,4-naphthoquinone, aromatic aldehydes, and 2-naphthol as synthetic inputs, using InCl3 a catalyst under solvent-free conditions. Most of the obtained ortho-quinonic adducts were cytotoxic against HEL and MCF-7 tumoral cell lines. 相似文献

β‐Hydroxy thiocyanates and β‐azidoalchols were obtained in excellent yields via GaCl3‐promoted highly regioselective ring opening of epoxides with ammonium thiocyanate or sodium azide in water. The present method is very rapid and equally compatible for both ammonium thiocyanate and sodium azide. 相似文献

A novel, highly efficient, single‐step synthesis of subphthalocyanines using microwave irradiation of phthalonitrile and boron trichloride in 1‐chloronaphthalene was accomplished for the first time. This provides a new preparative method for the synthesis of subphthalocyanines with reduced reaction times and improved yields. 相似文献

A mild and efficient condensation reaction of indoles with various aldehydes and ketones under catalysis of antimony trichloride (SbCl3) afforded biologically important bis(indolyl)methanes in good yield. The structures of all the newly synthesized compounds were elucidated on the basis of IR, 1H NMR and mass spectral data. 相似文献

The synthesis and structure of antimony(III) tripyrazolinates complexes with bidentate N,O, Schiff base pyrazoline ligands are reported. Four new coordination complexes incorporating antimony have been synthesized and characterized by spectroscopic methods (IR, 1 H NMR, 13 C NMR), molecular weight, and elemental analysis. Novel complexes of the type Sb(C 15 H 12 N 2 OX) 3 have been synthesized in dry benzene by the reaction of SbCl3 and the sodium salt of pyrazoline, NaC 15 H 12 N 2 OX, [where X = H (1), CH 3 (2), OCH 3 (3), and Cl (4)] in 1:3 molar ratio. The 3(2′ -hydroxyphenyl)-5-(4-substituted aryl) pyrazoline behaves as a bidentate ligand and coordinates to antimony through oxygen and nitrogen atoms, leading to distorted pentagonal bipyramidal structure. The antimicrobial properties of antimony are greatly enhanced when antimony is combined with this pyrazoline ligand. Compounds were screened against different bacteria (B. licheniformis and K. pneumonia) and fungi (Aspergillus niger and Penicillium notatum), and show potential activities. 相似文献
