PODANDES -- X-RAY DIFFRACTION ANALYSIS -- ACETIC ACID -- ORGANIC ACIDS
Аннотация: 1,8-Bis(diisothiosemicarbazido)-3,6-dioxaoctane have been synthesized by subsequent treatment of 2,2 -(ethylenedioxy)bisethylamine with carbon disulfide, sodium chloroacetate, and hydrazine hydrate. 1,8-Bis- (diisothiosemicarbazido)-3,6-dioxaoctane has reacted with lithium 1,1-difluoropenta-2,4-dionate in glacial acetic acid to yield 1,8-bis[5R*,5 R*(5-hydroxy-5-difluoromethyl-4,5-dihydro-3-methyl-1H-pyrazol-1-yl)-1-carbothioamido]-3,6-dioxaoctane. The molecular and crystal structure of the product has been determined by X-ray diffraction analysis.

Аннотация: General method for preparation of high yields of novel N-protected carborane amino acid derivatives, 3-acylamino-1-carboxymethyl-2-R-o-carboranes (R = H, Me, Ph), is reported. The synthesis starts from readily available 3-amino-o-carboranes and includes the protection of amino group, introduction of carboxymethyl function to the carbon atom of polyhedron via the metallation of carborane CH bond with sodium amide in liquid ammonia, and treatment of corresponding sodium carboranes with sodium bromoacetate. Deprotection of N-acylated carborane amino acids is studied in acidic media. Depending on the procedure employed, closo- or nido-carborane amino acids were obtained

Аннотация: Radical species generated from 5-aryl-substituted 1-ethyl-2,3-dicyano-1,4-diazinium salts by action of sodium iodide undergo dimerization into [2,2?]bipyrazinyl derivatives, as evidenced by NMR and X-ray crystallography data. The pyrazinyl radicals can also be involved into the addition reaction on the C-C triple bond, thus demonstrating a new synthetic route to modify the structure of pyrazines. The structures of E- and Z-isomers of 1-(1?,2?-dihydropyrazinyl-2?)-2-iodoethenes have been proved by 1H and 13C NMR spectroscopy and X-ray analysis

Аннотация: 1,2-Bis(azidomethyl)-о-carborane and 1,7-bis(azidomethyl)-m-carborane, prepared from the corresponding carboranylmethyl triflates and sodium azide, were conveniently functionalized by azide–alkyne cycloaddition affording novel bis[(1,2,3-triazolyl)methyl]carborane derivatives. Regiospecificity of this process was achieved by employing copper(II) acetate hydrate. Reaction of bis[(1,2,3-triazolyl)methyl]carborane derivatives with MeI yielded 3-methyl-1,2,3-triazolium carborane salts

SOL-GEL METHOD -- ZIRCONIUM OXYCHLORIDE -- SILICA-ZIRCONIA XEROGELS
Аннотация: The composite silica-zirconia xerogels have been prepared via sol-gel method using zirconium oxychloride, oxynitrate, acetate and sodium silicate as the precursors. The prepared materials have been characterized using FTIR, TG/DTA, EDX and surface area analyses. It has been established that surface area of silica-zirconia xerogels significantly depends on the zirconium source, but phase transitions and structural features of the xerogels seem to be unaffected by the choice of the zirconia precursor. Prepared xerogels increase the activity of chiral inductor in the asymmetric Biginelli reaction. The anion of the zirconium salt adsorbed on the surface of the synthesized material and the presence of Si-O-Zr heterolinkages determines the reaction yield. The highest chemo- and enantioselectivity towards formation of ee isomer have been provided by the catalyst prepared from zirconium oxychloride.
