Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. 51166-71-3, Name is 2,6-Di-O-methyl-β-cyclodextrin, SMILES is COC[C@@H]1[C@]2([H])[C@@H]([C@@H](OC)[C@](O[C@]3([H])[C@H](O[C@@](O[C@]4([H])[C@H](O[C@@](O[C@]5([H])[C@H](O[C@@](O[C@@]6([H])[C@H](O)[C@@H](OC)[C@@](O[C@@H]6COC)([H])O[C@@]7([H])[C@H](O)[C@@H](OC)[C@@](O[C@@H]7COC)([H])O[C@@]8([H])[C@H](O)[C@@H](OC)[C@@](O[C@@H]8COC)([H])O2)([H])[C@H](OC)[C@H]5O)COC)([H])[C@H](OC)[C@H]4O)COC)([H])[C@H](OC)[C@H]3O)COC)([H])O1)O, in an article , author is Celik, Mehmet A., once mentioned of 51166-71-3, Category: dioxoles.

1,3-Dioxole derivatives were synthesized from copper(II)-catalyzed cyclization reactions of carbonyl ylides derived from 3-methylenebicyclo[2.2.1]heptan-2-one and dimethyl diazomalonate. The reaction mechanisms leading to all possible products have been extensively investigated by density functional theory. The generally accepted mechanism proposed by Doyle(12) for the carbene transformation reactions were applied to this system for the first time to shed light on the reaction mechanism and to understand the catalytic activity of Cu(acac)(2). Calculations have shown that the reaction mechanisms leading to different products greatly depend on the conformations of copper-stabilized carbonyl ylides, which are treated as reactants in our calculations. The conformational effects and donor-acceptor type stabilizations between the catalyst and the carbonyl ylide observed in the reactants and the transition state geometries seem to be the main reasons for the observed product selectivity. Our theoretical results are in good agreement with the experimental results, and the calculations successfully predict the experimental 75:25 product distribution.

The FT-IR and FT-Raman spectra of (E)-1-(1,3-benzodioxol-5-yl)-4,4-dimethylpent-1-en-3-one were recorded and analyzed experimentally and theoretically. The observed experimental and theoretical wavenumbers were assigned using potential energy distribution. The NLO properties were evaluated by the determination of first and second hyperpolarizabilities of the title compound. From the frontier molecular orbital study, the HOMO centers over the entire molecule except the methyl groups, while the LUMO is over the entire molecule except the CH2 group with the dioxole ring and one of the methyl groups. From the MEP plot, it is evident that the negative region covers the carbonyl and C=C groups and the positive region is over CH2 groups. The Fukui functions are also reported. The calculated geometrical parameters are in agreement with the XRD results. From the molecular docking study, the docked ligand title compound forms a stable complex with the androgen receptor and gives a binding affinity value of -8.1 kcal/mol and the results suggest that the compound might exhibit inhibitory activity against androgen receptor.

Fluoropolymer films, such as Teflon(TM)-TFE [poly(tetrafluoroethylene)], Teflon(TM)-FEP [copolymer of tetrafluoroethylene and hexafluoropropylene], Teflon(TM)-PFA [copolymer of tetrafluoroethylene and perfluoro(propyl vinyl ether)], and PCTFE [poly(chlorotrifluoroethylene)], are reduced by the mild reducing agent benzoin dianion/DMSO, while Teflon(TM)-AF [copolymer of tetrafluoroethylene and perfluoro-2,2-dimethyl-1,3-dioxole] is unreactive. The reduction makes the films adherable toward epoxy resins, the adhesive strength decreasing in the order PCTFE > PFA greater than or equal to FEP > PTFE. Surprisingly, Teflon(TM)-AF films are totally inert except when the TFE content is high, and in these cases, the adhesive strength of Teflon(TM)-AF is close to that of PTFE. The surfaces of PTFE, FEP and PFA films are further modified by first treating these films with the benzoin dianion/DMSO reagent and then with an excess of sodium salts of mercaptans. Reactive PTFE films that are light colored with a metallic luster are formed rather than the dark, metallic color typical of PTFE surface reduction without mercaptan treatment. These films have poor adhesion toward epoxy resins but good adhesion toward gold applied by sputtering. FEP and PFA films behaved similarly. These results are attributed to the incorporation of sulfur onto the reduced surface. Unreduced fluoropolymer films reacted with only sodium mercaptan fail to show C-S bond incorporation. This newly developed method can be used to selectively metallize the fluoropolymer film surface with gold layers and affords very high conductivity of the metallized regions.

In the title indole derivative, C17H15NO4S, the fused dioxolo-indole system is essentially planar [r.m.s. deviation of the 12 fitted atoms = 0.0249 angstrom] and is effectively perpendicular to the appended 4-tolyl ring, forming a dihedral angle of 89.95 (6)degrees. Overall, the molecule has the shape of the letter L. In the crystal, supramolecular layers in the ab plane are formed via weak 4-tolyl-C-H center dot center dot center dot pi(C-6-ring of indole) and S-O center dot center dot center dot pi (1,3-dioxole) contacts. The aforementioned interactions along with interatomic H center dot center dot center dot H and H center dot center dot center dot O contacts are all shown to make significant contributions to the calculated Hirshfeld surfaces.

Nanocomposite membranes based on nano-sized SiO2 particles with chemical coupling to the polymer matrix are described with special emphasis on gas permeation properties. In this paper, poly(ether imide) with reactive imide rings in the backbone was used as the matrix to which the SiO2 particles were chemically bonded via an amine-containing silane coupling agent. Four types of nanocomposite membranes were prepared by solution casting and melt processing and characterized in terms of morphology and void volume formed due to adding SiO2 particles. The relative gas permeability of the nanocomposite with chemical coupling to matrix was decreased by the presence of SiO2 particles. Diffusion coefficients computed from time lag data also decreased with SiO2 content. However, solubility coefficients computed by dividing the experimental permeability by the diffusivity obtained from the observed time lag increased with SiO2 content contrary to simple composite theory. These permeation properties are discussed in terms of the void volume fraction estimated by density observations. In addition, TEM and SEM were used to explore the morphology of these nanocomposite membranes. (c) 2006 Elsevier Ltd. All rights reserved.

A medium size and rigid molecule (2,3-naphto-1,3-dioxole) has been selected for this study because full anisotropic reorientation is expected and because its symmetry elements dictate the orientation of the rotation-diffusion tensor. NMR measurements include direct cross-relaxation rates (which yield the three rotation-diffusion coefficients by assuming the length of CH bonds) and remote cross-relaxation rates (which, by using these rotation-diffusion coefficients, yield distances between a given carbon and remote protons). Two different solvents have been used: carbon disulfide and dimethyl sulfoxide, In both solvents, the same type of reorientation anisotropy is observed although with different ratios of rotation-diffusion coefficient values, presumably due to specific intermolecular interactions undergone by the dioxole ring. This would also explain geometrical variations at the level of this moiety. (C) 2002 Published by Elsevier Science B.V.

Synthesis of fluorodioxole olefin monomers by thermal decomposition of fluorinated dioxolane carboxylic acid and the corresponding acyl chloride was explored. Complex product formation is observed, including acyl fluoride from Cl-F exchange, the hydro-dioxolane from proton abstraction, the cyclic ether ketone from dioxolane ring opening, and the epoxy acid fluoride from thermal rearrangement. The product distribution is strongly dependent upon reaction conditions. The main influential factors include the reaction temperature, the base used for the reaction, the presence or absence of solvent, and the counter ion associated with the intermediate salt. A mechanism is proposed to rationalize both the results and the product distribution. Methods to make authentic samples for product analysis are reported.
