Abstract:

The triethyloxonium tetrafluoroborate/1,2-dimethoxyethane (TEO/DME) mixture is a versatile and cheap substitute for trimethyloxonium tetrafluoroborate in O-methylations of pyrrolin-2-ones, quinolones, acridones, and 1-oxo-β -carbolines. Undesired O-ethylation can be avoided by preincubation of triethyloxonium tetrafluoroborate and 1,2-dimethoxyethane for 1 h, prior to addition of the substrate. In the course of these investigations it was found that the structures assigned to the alkaloids taraxacine A and B are erroneous.

Abstract:

Under normal conditions, 1,2-dimethoxyethane (DME) is a colorless and transparent liquid with a faint odor of ether, very soluble in water, charac-terized by a high vapor pressure. It belongs to the group of alkyl ethers solvents, derivatives of eth-ylene glycol. 1,2-Dimethoxyethane is used as an ex-cipient in preparing and processing industrial chemicals, in the production of fluoric polymers and as a solvent and cleaning agent in the microe-lectronics and printing industries. In the literature there are no data on the acute and chronic toxicity of 1,2-dimethoxyethane. However, long-term epidemiological studies on compounds of similar chemical structure suggest that human exposure to ethylene glycol alkyl ethers can ad-versely affect fertility and fetal development, and hematological parameters. The aim of this study was to develop and validate a sensitive method for determining concentrations of 1,2-dimethoxyethane in workplace air in the range from 1/20 to 2 MAC values, in accordance with the requirements of Standard No. PN-EN 482+A1: 2016-1. The study was performed using a gas chromato-graph (GC). A 7890B Agilent Technologies gas chromatograph with a 5977A mass spectrometry detector (MSD), HP PONA (50 m; 0,2 mm; 0,5 μm) capillary analytical column, auto sampler and Mass Hunter software was used for chromato-graphic separations. The method is based on the adsorption of 1,2-di-methoxyethane on charcoal, desorption with di-chloromethane and GC/MSD analysis of the re-sulting solution. Extraction efficiency of 1,2-di-methoxyethane from charcoal was 96.4%. Samples of 1,2-dimethoxyethane can be stored in refrigera-tor for up to 28 days. The use of a HP-PONA capil-lary column enabled selective determination of 1,2-dimethoxyethane in a mixture of dichloromethane, toluene, carbon disulfide, ethylene and propylene glycol and other compounds. The method is linear (r = 0.9999) within the inves-tigated working range from 5 to 200 μg/ml, which is equivalent to air concentrations from 0.5 to 20 mg/m3 for a 10-L air sample. The limit of quan-tification (LOQ) is 1,306 μg/ml. The analytical method described in this paper ena-bles selective determination of 1,2-dimethoxye-thane in workplace atmosphere in presence of other compounds at concentrations from 0.5 to 20 mg/m3 (1/20 ÷ 2 MAC value). The method is precise, accurate and it meets the criteria for proce-dures for measuring chemical agents listed in Standard No. PN-EN 482+A1: 2016-1. The method can be used for assessing occupational exposure to 1,2-dimethoxyethane and associated risk to work-ers’ health. The developed method of determining 1,2-di-methoxyethane has been recorded as an analytical procedure (see Appendix).

Abstract:

The use of baker’s yeast to reduce ethyl 2-oxo-4-phenylbutyrate (EOPB) in conventional biphasic systems is hindered by low productivities due to mass transfer resistance between the biocatalyst and the substrate partitioned into two different phases. To overcome the limitation, a new reaction-separation coupling process (RSCP) was configured in this study, based on the novel thermosensitive ionic liquids (ILs) with polyoxyethylene-tail. The solubility of ILs in common solvents was investigated to configure the unique thermosensitive ionic liquids–solvent biphasic system (TIBS) in which the reduction was performed. [(CH3)2N(C2H5)(CH2CH2O)2H][PF6] (c2) in 1,2-dimethoxyethane possesses the thermosensitive function of homogeneous at lower temperatures and phase separating at higher temperatures. The phase transformation temperature (PTT) of the mixed system of c2/1,2-dimethoxyethane (v/v, 5:18) was about 33 °C. The bioreaction takes place in a “homogeneous” liquid phase at 30 °C. At the end of each reduction run, the system temperature is increased upon to the PTT, while c2 is separated from 1,2-dimethoxyethane with turning the system into two phases. The enantiomeric excesses (e.e.) of ethyl (R)-2-hydroxy-4-phenylbutyrate ((R)-EHPB) increased about 25~30% and the yield of ethyl-2-hydroxy-4-phenylbutyrate (EHPB) increased 35% in TIBS, compared with the reduction in 1,2-dimethoxyethane. It is expected that the TIBS established in this study could provide many future opportunities in the biocatalysis.

Abstract:

In recent years we have focused our efforts on investigating various binary mixtures containing carbon dioxide to find the best candidate for CO2 capture and, therefore, for applications in the field of CCS and CCUS technologies. Continuing this project, the present study investigates the phase behavior of three binary systems containing carbon dioxide and different oxygenated compounds. Two thermodynamic models are examined for their ability to predict the phase behavior of these systems. The selected models are the well-known Peng–Robinson (PR) equation of state and the General Equation of State (GEOS), which is a generalization for all cubic equations of state with two, three, and four parameters, coupled with classical van der Waals mixing rules (two-parameter conventional mixing rule, 2PCMR). The carbon dioxide + ethyl acetate, carbon dioxide + 1,4-dioxane, and carbon dioxide + 1,2-dimethoxyethane binary systems were analyzed based on GEOS and PR equation of state models. The modeling approach is entirely predictive. Previously, it was proved that this approach was successful for members of the same homologous series. Unique sets of binary interaction parameters for each equation of state, determined for the carbon dioxide + 2-butanol binary model system, based on k12–l12 method, were used to examine the three systems. It was shown that the models predict that CO2 solubility in the three substances increases globally in the order 1,4-dioxane, 1,2-dimethoxyethane, and ethyl acetate. CO2 solubility in 1,2-dimethoxyethane, 1.4-dioxane, and ethyl acetate reduces with increasing temperature for the same pressure, and increases with lowering temperature for the same pressure, indicating a physical dissolving process of CO2 in all three substances. However, CO2 solubility for the carbon dioxide + ether systems (1,4-dioxane, 1,2-dimethoxyethane) is better at low temperatures and pressures, and decreases with increasing pressures, leading to higher critical points for the mixtures. By contrast, the solubility of ethyl acetate in carbon dioxide is less dependent on temperatures and pressures, and the mixture has lower pressures critical points. In other words, the ethers offer better solubilization at low pressures; however, the ester has better overall miscibility in terms of lower critical pressures. Among the binary systems investigated, the 1,2-dimethoxyethane is the best solvent for CO2 absorption.

Abstract:

In this paper, a new type lithium hexafluorophosphate (LiPF6) complex was prepared with a new method using phosphorus pentachlorine (PCl5), lithium fluoride (LiF) and 1,2-dimethoxyethane (C4H10O2). The structure of the complex was carefully characterized by FTIR, TG-DTG,1H NMR and31P NMR. FTIR results indicate that the synthesized complex is consisted of LiPF6and C4H10O2. Chemical analysis shows that the content of LiPF6in the complex is about 45%, which could infer that the mole ratio of LiPF6and LiPF6(C4H10O2)2in the complex is 1:2. The results of1H NMR and31P NMR further confirm the composition of the complex and determine the structure. The molecular formula of the LiPF6complex is LiPF6(C4H10O2)2. Thermal analysis shows that the strong decomposition peaks of the complex appear at 75°C and 175°C. LiPF6(C4H10O2)2may be used in the electrolyte of the lithium ion battery which 1,2-dimethoxyethane is permitted or broke down into LiPF6after further preparation.

Abstract:

Two new mononuclear cationic complexes in which the TbIIIion is bis-chelated by the tripodal alcohol 1,1,1-tris(hydroxymethyl)propane (H3LEt, C6H14O3) were prepared from Tb(NO3)3·5H2O and had their crystal and molecular structures solved by single-crystal X-ray diffraction analysis after data collection at 100 K. Both products were isolated in reasonable yields from the same reaction mixture by using different crystallization conditions. The higher-symmetry complex dinitratobis[1,1,1-tris(hydroxymethyl)propane]terbium(III) nitrate dimethoxyethane hemisolvate, [Tb(NO3)2(H3LEt)2]NO3·0.5C4H10O2,1, in which the lanthanide ion is 10-coordinate and adopts ans-bicapped square-antiprismatic coordination geometry, contains two bidentate nitrate ions bound to the metal atom; another nitrate ion functions as a counter-ion and a half-molecule of dimethoxyethane (completed by a crystallographic twofold rotation axis) is also present. In product aquanitratobis[1,1,1-tris(hydroxymethyl)propane]terbium(III) dinitrate, [Tb(NO3)(H3LEt)2(H2O)](NO3)2,2, one bidentate nitrate ion and one water molecule are bound to the nine-coordinate terbium(III) centre, while two free nitrate ions contribute to charge balance outside the tricapped trigonal-prismatic coordination polyhedron. No free water molecule was found in either of the crystal structures and, only in the case of1, dimethoxyethane acts as a crystallizing solvent. In both molecular structures, the two tripodal ligands are bent to one side of the coordination sphere, leaving room for the anionic and water ligands. In complex2, the methyl group of one of the H3LEtligands is disordered over two alternative orientations. Strong hydrogen bonds, both intra- and intermolecular, are found in the crystal structures due to the number of different donor and acceptor groups present.

Abstract:

The significant variety in the crystal structures of rare-earth carboxylate complexes is due to both the large coordination numbers of the rare-earth cations and the ability of the carboxylate anions to form several types of bridges between rare-earth metal atoms. Therefore, these complexes are represented by mono-, di- and polynuclear complexes, and by coordination polymers. The interaction of LnCl3(thf)x(Ln = Eu or Y; thf is tetrahydrofuran) with sodium or diethylammonium diphenylacetate in methanol followed by recrystallization from a DME/THF/hexane solvent mixture (DME is 1,2-dimethoxyethane) leads to crystals of the non-isomorphic dinuclear complexes tetrakis(μ-2,2-diphenylacetato)-κ4O:O′;κ3O,O′:O′;κ3O:O,O′-bis[(1,2-dimethoxyethane-κ2O,O′)(2,2-diphenylacetato-κ2O,O′)europium(III)], [Eu(C14H11O2)6(C4H10O2)2], (I), and tetrakis(μ-2,2-diphenylacetato)-κ4O:O′;κ3O,O′:O′;κ3O:O,O′-bis[(1,2-dimethoxyethane-κ2O,O′)(2,2-diphenylacetato-κ2O,O′)yttrium(III)], [Y(C14H11O2)6(C4H10O2)2], (II), possessing monoclinic (P21/c) symmetry. The [Ln(Ph2CHCOO)3(dme)]2molecule (Ln = Eu or Y) lies on an inversion centre and exhibits three different coordination modes of the diphenylacetate ligands, namely bidentate κ2O,O′-terminal, bidentate μ2-κ1O:κ1O′-bridging and tridentate μ2-κ1O:κ2O,O′-semibridging. The terminal and bridging ligands in (I) are disordered over two positions, with an occupancy ratio of 0.806 (2):0.194 (2). The interaction of EuCl3(thf)2with Na[Ph3CCOO] in methanol followed by crystallization from hot methanol produces crystals of tetrakis(methanol-κO)tris(2,2,2-triphenylacetato)-κ4O:O′;κO-europium(III) methanol disolvate, [Eu(C19H15O2)3(CH3OH)4]·2CH3OH, (III)·2MeOH, with triclinic (P\overline{1}) symmetry. The molecule of (III) contains twoO,O′-bidentate and oneO-monodentate terminal triphenylacetate ligand. (III)·2MeOH possesses one intramolecular and four intermolecular hydrogen bonds, forming a [(III)·2MeOH]2dimer with two bridging methanol molecules.

Abstract:

Cobalt(II) chloride catalyzed oxidation of 2-substituted 1,3-dioxolanes in 1,2-dimethoxyethane afforded formate esters and acids in high yields. It was found that the presence of catalytic amounts of ZnCl2 increased the rate of oxidation. A free-radical mechanism is proposed, involving participation of superoxocobalt, and the esterification of the alcohol and acid.

Abstract:

Thermodynamic interactions in 2-methoxyethanol (component 1)+1,2-dimethoxyethane (component 2) binary mixtures have been studied in terms of the excess molar volume from the densities, measured at 19 temperatures between -10 and 80°C, for nine binary mixtures covering the whole miscibility field expressed by the mole fraction 0 ≤ X1 ≤ 1. Excess molar volumes are discussed in terms of induced conformational changes in each component in the presence of the other. The present findings support a hypothesis about the formation of a solvent-cosolvent complex species which has a well defined 1:1 stoichiometric composition and is thermostable under the experimental conditions.

Abstract:

A previous analysis [Fatilaet al.(2012).Dalton Trans.41, 1352–1362] of the title complex, [Ce2(C5HF6O2)6(C4H10O2)3], had identified it as Ce(hfac)3(dme)1.5according to the1H NMR integration [hfac = 1,1,1,5,5,5-hexafluoroacetylacetonate (1,1,1,5,5,5-hexafluoro-4-oxopent-2-en-2-olate) and dme = 1,2-dimethoxyethane]; however, it was not possible to determine the coordination environment unambiguously. The structural data presented here reveal that the complex is a binuclear species located on a crystallographic inversion center. Each CeIIIion is coordinated to three hfac ligands, one bidentate dme ligand and one monodentate (bridging) dme ligand, thus giving a coordination number of nine (CN = 9) to each CeIIIion. The atoms of the bridging dme ligand are unequally disordered over two sets of sites. In addition, in two of the –CF3groups, the F atoms are rotationally disordered over two sets of sites. This is the first crystal structure of a binuclear lanthanide β-diketonate with a bridging dme ligand.

Abstract:

The complexes [MoNCl3·DME] and [WNCl3·DME] (DME = 1,2-dimethoxyethane) have been prepared by the reaction of the nitride chlorides MNC13 with equimolar amounts of DME in CH2Cl2 suspensions. They form orangered, moisture sensitive crystals, which are soluble in organic solvents. The molybdenum complex has been characterized by a crystal structure determination. Space group Pbca, Z = 8, structure solution with 1781 observed unique reflections, R = 0.031. Lattice dimensions at –60°C: a = 738.6(1), b = 1182.2(1), c = 2314.1(1) pm. [MoNCl3·DME] forms monomeric complexes with chelating DME molecules and Mo–O bond lengths of 215.4(4) and 247.4(4) pm, the longer one being in trans-position of the nitrido ligand. The MoN bond length of 163.3(5) pm suggests a triple bond.
