The enantiomers of spiro[benzo-1,3-dioxole-2,9′-bicyclo[3.3.1]nonan]-2′-one 2 and the corresponding diastereomeric exo-2′- and endo-2′-hydroxy acetals 3a,b obtained from this monoacetal were solved by HPLC on a swollen microcrystalline triacetylcellulose column. The absolute configuration of the enantiomers of 2 and 3a,b was assigned based on the signs of the Cotton effect and employing the octant rules for the carbonyl and the aromatic chromophores The low intensity of the band at 290 nm in the CD spectrum of monoacetal 2 was accounted far by the interaction of the carbonyl and aromatic chromophores.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

In this paper is presented a study on the effects of physical treatments, namely electron beam irradiation or fluorination, on a perfluoropolymer copolymer of tetrafluoroethylene with 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole (Hyflon (R) AD copolymer). The analysis has been carried out by means of IR spectroscopy and quantum chemical modeling based on density functional theory; this combined experimental/ theoretical approach has proven effective for the interpretation of previously unassigned IR bands, which are associated to functional groups generated by polymer degradation and chain scission. We performed a systematic screening of chemical groups and structures compatible with degradation pathways that are possible from the chemical point of view: the chemical mechanisms and the correlation with the spectroscopic experimental data (both frequency and intensity) provide guidelines in understanding the phenomena. Moreover, the spectroscopic experimental/theoretical and chemical approaches allowed us to identify some chemical structures responsible for the unassigned IR bands in the C=O stretching frequency region above 1800 cm(-1), which is typical for carbonyl groups in fluorinated systems.

Four amphetamine derivatives bearing a methylenedioxy group at positions 3 and 4 of the benzene ring and differing in their substitution at C(6) were studied by differential pulse voltammetry in aqueous media. These experiments showed a single oxidation peak for the C(6)-H, -Br and -Cl compounds, while the C(6)-NO2 analogue was not oxidized. The oxidation peak is interpreted as due to the removal of one electron from the aromatic electrophore with formation of a radical cation stabilized by the dioxole ring. The linear relationship between the peak current and the concentration of the derivatives is appropriate for development of a quantitative method for their determination. pK’ values were determined using both electrochemical and spectrophotometric methods.

DB-6, with an IUPAC name of (Z)-5-(2,4-di-tert-butyl-6-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl)-5′-methyl-7,7′-dimethoxy-[4,4′-bibenzo[ d][1,3] dioxole]-5,5′-dicarboxylate,is an investigational agent for acute liver failure. The focus of this study is the identification and characterization of major unknown impurities in DB-6 bulk drug samples. Four major impurities of DB-6 were detected by a high-performance liquid chromatography (HPLC) method and designated as IMP-I, IMP-II, IMP-III and IMP-IV. Accurate masses of these impurities were determined by using a Q-TOF mass spectrometer. Based on chromatographic, spectrometric data and plausible chemical transformation mechanism, the structures of IMP-I, IMP-II, IMP-III and IMP-IV were identified, respectively, as bifendate, (E)-5-(2,4-ditert- butyl-6-((2,4-dioxothiazolidin-5-ylidene) methyl) phenyl)-5′-methyl-7,7′- dimethoxy-[4,4′-bibenzo[d][1,3] dioxole]-5,5′-dicarboxylate, (Z)-5( 3,5-di-tert-butyl-2-hydroxybenzylidene) thiazolidine-2,4-dione and bis(2,4-di-tert-butyl-6-((Z)-(2,4-dioxothiazolidin-5-ylidene) methyl)phenyl)- 7,7′-dimethoxy-[4,4′-bibenzo[d][1,3] dioxole]-5,5′-icarboxylate. The impurities were isolated by preparative-HPLC or preparative high-speed counter-current chromatography and their structures were confirmed by NMR spectroscopy.

Carbonyl ylides arising from ethyl acetodiazoacetate/dimethyl diazomalonate and a,beta-enones with mainly s-cis conformations underwent disrotatory cyclization to produce dihydrofuran derivatives. This process proved to be sensitive to steric effects. The corresponding ylides arising from rather s-trans a,beta-enals yielded dioxole derivatives. The mechanisms of the reactions are discussed.

With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation for quality and ethical publishing we’ve spent the past two centuries establishing. 14618-80-5, Name is (R)-2-((Benzyloxy)methyl)oxirane, SMILES is [C@@H]1(COCC2=CC=CC=C2)OC1, in an article , author is Merkel, TC, once mentioned of 14618-80-5, Quality Control of (R)-2-((Benzyloxy)methyl)oxirane.

The solubility and permeability of H-2, O-2, N-2, CO2, CH4, C2H6, C3H8, CF4, C2F6, and C3F8 in TFE/BDD87, a random copolymer prepared from 87 mol % 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole [BDD] and 13 mol % tetrafluoroethylene [TFE], are reported as a function of temperature and pressure. Sorption isotherms of all penetrants except hydrogen are concave to the pressure axis and are well described by the dual-mode model. Hydrogen exhibits linear sorption isotherms. In contrast to previous results in hydrocarbon-rich polymers, the solubility of perfluorocarbon penetrants is higher in TFE/BDD87 than that of their hydrocarbon analogues. The solubility of all penetrants in TFE/BDD87 decreases with increasing temperature. Enthalpies of sorption become more negative as penetrant size increases. Fluorocarbon enthalpies of sorption at infinite dilution are significantly more exothermic than those of their hydrocarbon analogues, suggesting more favorable interactions between fluorocarbon penetrants and perfluorinated TFE/BDD87 than between hydrocarbon penetrants and this polymer. Perfluorocarbon permeability coefficients are nearly an order of magnitude lower than those of their hydrocarbon analogues due to the larger size of the fluorocarbons and their subsequently lower diffusivities. The permeability of TFE/BDD87 increases with increasing temperature, indicating that activation energies of permeation (E-p) are positive. E-p values in TFE/BDD87 are smaller than those of conventional glassy polymers. Diffusion coefficients of the lower sorbing gases (O-2, N-2, CO2, CH4, CF4) exhibit a concentration dependence that is consistent with dual-mode transport in unplasticized glassy polymers. For more strongly sorbing C2H6, C3H8, C2F6, and C3F8, diffusion coefficients increase exponentially with increasing penetrant concentration, suggesting plasticization. Activation energies of diffusion in TFE/BDD87 are positive and increase linearly with penetrant diameter squared. Relative to conventional glassy polymers, E-D values in TFE/BDD87 are low. However, E-D is larger than Delta H-S. TFE/BDD87 is easily plasticized by the larger, more soluble penetrants and is susceptible to penetrant-induced conditioning. The level of conditioning is highest for the largest, most soluble penetrant examined (C3F8), and the conditioned state gradually relaxes toward that of the as-cast state.
