Abstract:

In this study, we report a detailed experimental and theoretical investigation of three glycol derivatives, namely ethane-1,2-diol, 2-methoxyethan-1-ol and 1,2-dimethoxy ethane. For the first time, the X-ray spectra of the latter two liquids was measured at room temperature, and they were compared with the newly measured spectrum of ethane-1,2-diol. The experimental diffraction patterns were interpreted very satisfactorily with molecular dynamics calculations, and suggest that in liquid ethane-1,2-diol most molecules are found in gauche conformation, with intramolecular hydrogen bonds between the two hydroxyl groups. Intramolecular H-bonds are established in the mono-alkylated diol, but the interaction is weaker. The EDXD study also evidences strong intermolecular hydrogen-bond interactions, with short O···O correlations in both systems, while longer methyl-methyl interactions are found in 1,2-dimethoxy ethane. X-ray studies are complemented by micro Raman investigations at room temperature and at 80 °C, that confirm the conformational analysis predicted by X-ray experiments and simulations.

Abstract:

A new one-dimensional NiIIcoordination polymer of 1,3,5-tris(imidazol-1-ylmethyl)benzene, namelycatena-poly[[aqua(sulfato-κO)hemi(μ-ethane-1,2-diol-κ2O:O′)[μ3-1,3,5-tris(1H-imidazol-1-ylmethyl)benzene-κ3N3,N3′,N3′′]nickel(II)] ethane-1,2-diol monosolvate monohydrate], {[Ni(SO4)(C18H18N6)(C2H6O2)0.5(H2O)]·C2H6O2·H2O}n, was synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The NiIIcation is coordinated by three N atoms of three different 1,3,5-tris(imidazol-1-ylmethyl)benzene ligands, one O atom of an ethane-1,2-diol molecule, by a sulfate anion and a water molecule, forming a distorted octahedral NiN3O3coordination geometry. The tripodal 1,3,5-tris(imidazol-1-ylmethyl)benzene ligands link the NiIIcations, generating metal–organic chains running along the [100] direction. Adjacent chains are further connected by O—H...O hydrogen bonds, resulting in a two-dimensional supermolecular architecture running parallel to the (001) plane. Another water molecule and a second ethane-1,2-diol molecule are non-coordinating and are linked to the coordinating sulfate ionsviaO—H...O hydrogen bonds.

Abstract:

Kinematic viscosities (v) of pure ethane-1,2-diol (component 1) and of nine mixtures with water (component 2) were measured at 19 temperatures ranging from -10 to +80°C, and for binary compositions covering the whole miscibility field expressed by the relation 0 ≤ X1 ≤ 1. The property fitted some empirical equations in terms of the dependences v = v(T) and v(X1), where T is the thermodynamic temperature and X1 is the mole fraction of ethane-1,2-diol. Furthermore, the excess function (vE) and the excess Gibbs energy of activation of viscous flow (∆G*E) have been investigated. The trend of vE against binary composition of the mixtures shows negative deviations from ideal behaviour, while the contrary is true for ∆G*E The results indicate specific molecular interactions between the components, and an overview is given on the basis of the molecular dynamics of the pure species.

Full text

Abstract:

While the exploitation of the Sharpless asymmetric dihydroxylation as the source of chirality in the synthesis of acyclic molecules and saturated heterocycles has been tremendous, its synthetic utility toward chiral benzo-annulated heterocycles is relatively limited. Thus, in the search for wider applications of Sharpless asymmetric dihydroxylation-derived diols for the synthesis of benzo-annulated heterocycles, we report herein our studies in the asymmetric synthesis of (R)-1-((R)-6-fluorochroman-2-yl)ethane-1,2-diol, (R)-1-((S)-6-fluorochroman-2-yl)ethane-1,2-diol and (S)-6-fluoro-2-((R)-oxiran-2-yl)chroman, which have been used as late-stage intermediates for the asymmetric synthesis of the antihypertensive drug (S,R,R,R)-nebivolol. Noteworthy is that a large number of racemic and asymmetric syntheses of nebivolol and their intermediates have been described in the literature, however, the Sharpless asymmetric dihydroxylation has never been employed as the sole source of chirality for this purpose.

Abstract:

The self-assembly of coordination polymers and the crystal engineering of metal–organic coordination frameworks have attracted great interest, but it is still a challenge to predict and control the compositions and structures of the complexes. Employing multidentate organic ligands and suitable metal ions to construct inorganic–organic hybrid materials through metal–ligand coordination and hydrogen-bonding interactions has become a major strategy. Recently, imidazole-containing multidentate ligands that contain an aromatic core have received much attention. A new three-dimensional MnIIcoordination polymer based on 1,3,5-tris[(1H-imidazol-1-yl)methyl]benzene, namely poly[(ethane-1,2-diol-κO)(μ-sulfato-κ2O:O′){μ3-1,3,5-tris[(1H-imidazol-1-yl)methyl]benzene-κ3N:N′:N′′}manganese(II)], [Mn(SO4)(C18H18N6)(C2H6O2)]n, was synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Crystal structural analysis shows that there are two kinds of crystallographically independent MnIIcentres, each lying on a centrosymmetric position and having a similar six-coordinated octahedral structure. One is coordinated by four N atoms from four 1,3,5-tris[(1H-imidazol-1-yl)methyl]benzene (timb) ligands and two O atoms from two different bridging sulfate anions. The second is surrounded by two timb N atoms and four O atoms, two from sulfate anions and two from two ethane-1,2-diol ligands. The tripodal timb ligand bridges neighbouring MnIIcentres to generate a two-dimensional layered structure running parallel to theabplane. Adjacent layers are further bridged by sulfate anions, resulting in a three-dimensional structure with3,4,6-ctopology. Thermogravimetric analysis of the title polymer shows that it is stable up to 533 K. The first weight loss between 533 and 573 K corresponds to the release of coordinated ethane-1,2-diol molecules, and further decomposition occurred at 648 K.

Abstract:

The dielectric behaviour of binary mixtures of 1,2-dichloroethane (DCE)/ethane-1,2-diol (ED) and DCE/2-methoxyethanol (ME) has been studied at 19 temperatures in the range from -10 to +80°C. The DCE/ED system is immiscible, except in a narrow range near the ED-rich region. The DCE/ME system, which is completely miscible, has been investigated over the whole composition range. Fitting procedures have been applied in order to check the suitability of empirical or semiempirical functions of the type є(T), є(XI) and є(T,XI). Furthermore, the excess static dielectric constant, єE, has been evaluated in order to investigate the possibility of the existence of complex entities. A DCE.2ME species appears to be the only stable adduct.

The experimental data were analyzed by the Fuoss–Hsia equation, which provides further informative parameters such as the dissociation constant (K) of the ion pairs formed in solution, the limiting equivalent conductivity (Λ0), and the ion-size parameter (å). Thermodynamic behaviour of these electrolytes was derived from analysis of the K values. Single-ion conductivities were evaluated on the basis of the assumption of Ph4PBPh4 as reference electrolyte.

Abstract:

Kinematic viscosities (v) have been measured for pure ethane-1,2-diol, 1,4-dioxan and for nine of their mixtures covering the entire composition range and, where possible, at 19 temperatures from -10 to +80°C. The experimental values were converted into dynamic viscosities (η) and were correlated with temperature and binary composition by some empirical equations. Furthermore, the excess function ηE and the excess Gibbs energy of activation of viscous flow ΔG*E have been evaluated. Negative deviations from ideality are always observed for this binary system, this fact indicating strong specific interactions between unlike entities in solution to form stable solvent- cosolvent adducts. Activation enthalpies and entropies for viscous flow have been derived, and their dependence on binary composition is also discussed.

Abstract:

A sol-gel method based on in situ generation of mixed-metal chelates by complexing metal ions with ethane-1,2-diol in aqueous media has been elaborated to prepare lanthanide-ion containing garnets, Gd3Al5O12 (GAG) and La3Al5O12 (LAG). XRD patterns of the powders sintered at 1 000 °C revealed the formation of monophasic GAG. However, LAG does not form under the same experimental conditions. The phase composition of the samples was characterised by IR spectroscopy. Microstructural features of the polycrystalline garnets were studied by SEM.

Abstract:

In this discussion, we show that a static definition of a ‘bond’ is not viable by looking at a few examples for both inter- and intra-molecular hydrogen bonding. This follows from our earlier work (Goswami and Arunan,Phys. Chem. Chem. Phys.2009,11, 8974) which showed a practical way to differentiate ‘hydrogen bonding’ from ‘van der Waals interaction’. We report results fromab initioand atoms in molecules theoretical calculations for a series of Rg⋯HX complexes (Rg = He/Ne/Ar and X = F/Cl/Br) and ethane-1,2-diol. Results for the Rg⋯HX/DX complexes show that Rg⋯DX could have a ‘deuterium bond’ even when Rg⋯HX is not ‘hydrogen bonded’, according to the practical criterion given by Goswami and Arunan. Results for ethane-1,2-diol show that an ‘intra-molecular hydrogen bond’ can appear during a normal mode vibration which is dominated by the O⋯O stretching, though a ‘bond’ is not found in the equilibrium structure. This dynamical ‘bond’ formation may nevertheless be important in ensuring the continuity of electron density across a molecule. In the former case, a vibration ‘breaks’ an existing bond and in the later case, a vibration leads to ‘bond’ formation. In both cases, the molecule/complex stays bound irrespective of what happens to this ‘hydrogen bond’. Both these cases push the borders on the recent IUPAC recommendation on hydrogen bonding (Arunanet al. Pure. Appl. Chem.2011,831637) and justify the inclusive nature of the definition.

Abstract:

The associating behaviour of ethane-1,2-diol (component 1)+1,4-dioxan (component 2) in their binary mixtures has been investigated through their dielectric properties. The experimental measurements of the relative permittivity (є) in the temperature range -10 ≤ X1 ≤ 80 for nine binary mixtures covering the whole miscibility field 0 ≤ X1 ≤ 1 have been utilized to test empirical equations representing the functions є = є(T), є = є (X1) and є = є(T,X1). Furthermore, the excess mixing function, єE, has been evaluated to obtain qualitative and quantitative information about the possibility of 'solvent- cosolvent ' complex formation.

Abstract:

9,9-Dichloro-1,4-dihydro-4a,8a-methanonaphthalene (4) adds the electron-deficient dienophiles 4-phenyl-1,2,4-triazoline-3,5-dione, maleic anhydride and dimethyl acetylenedicarboxylate to the α-face to give adducts (5)-(7) respectively; the addition of the alkyne requires Lewis acid catalysis. Inverse electron-demand addition of 3,6-diphenyl-1,2,4,5-tetrazine to the monoene component of (4) in hydrophilic solvent (ethane-1,2-diol) is thwarted; the CCl2 bridge is ejected and the 1,4-dihydronaphthalene formed is captured to give (ultimately) phthalazine (16). Dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate adds to (4) to give the methanobenzophthalazine (17b).

Full text

Abstract:

The osmotic pressures of aqueous solutions of small non-electrolytes, namely ethane-1,2-diol, propane-1,2,3-triol, sucrose and raffinose , were found to be expressible by quadratic equations of the molar concentration, which indicate that these aqueous systems involve no term higher than the second virial coefficient A2. Analysis has shown that A2 mainly does not arise from non-ideality of the aqueous solutions, but its magnitude depends on the partial molar volume of the solute, more precisely on the molecular weight or van der Waals radius or volume of the solute in the aqueous solution.

Solvent effects on 2,6-dichloro-4-(2,4,6-triphenyl-pyridinium-1-yl)phenolate [ET (33) dye] and 7- diethylamino-3,4-benzophenoxazine-2-one (Nile Red) in binary mixtures of organic solvents (acetone, acetonitrile, propylene carbonate, methanol and ethane-1,2-diol) with 1,3-dialkyl imidazoliumbased ionic liquids were studied by UV-visible spectroscopy. Highly nonlinear behaviour of mixtures of alcohols and ionic liquids was found. A preferential solvation model was applied to the data obtained on solvatochromic shifts over the entire mixing range. It is fitting the data well for alcohol mixtures and for other solvent mixtures with different ionic liquids.
