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.

Computations were carried out employing the restricted Hartree-Fock (RHF) and density functional theory (DFT) methods to investigate the geometries and energies for the 1,3-dithiole-2-thione (DTT), 1,3-dithiole-2-one (DTO), 1,3-dioxole-2-thione (DOT), and 1,3-dioxole-2-one (DOO) molecules and their radical cations. The geometrical parameters of all the four molecules suggest a finite extent of extended conjugation across the molecules. The radical cations of the DTT and DOT molecules exhibit increased extent of conjugation compared to their neutral analogues. However, on going from the neutral DOO and DTO molecules to their radical cations, the extent of conjugation across the ions decreases and two unsaturated sites become isolated from each other. Requirement of the relaxation energy for the formation of radical cation is much lower for the DTT and DOT molecules compared to that for the DOO and DTO molecules. Smaller relaxation energy requirement favors minimal resistance to charge transport along the molecular stacking. Therefore, it is speculated that the DTT and DOT molecules are better molecular conductors as compared to the DOO and DTO molecules.

New research progress on 51166-71-3 in 2021. Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. In an article, author is Itoh, S, once mentioned the application of 51166-71-3, Electric Literature of 51166-71-3, Name is 2,6-Di-O-methyl-β-cyclodextrin, molecular formula is C56H98O35, molecular weight is 1331.3563, MDL number is MFCD00011616, category is dioxole. Now introduce a scientific discovery about this category.

An addition-cyclization reaction of nitroalkane anions with tricyclic o-quinones occurs in acetonitrile to yield the corresponding 1,3-dioxole derivatives. The heat of formation of the charge-transfer complex formed between the 2-nitropropane anion and 1,7-phenanthroline-5,6-dione is of greater magnitude than the observed activation enthalpy of the addition reaction. Since such a relationship could only arise when the charge-transfer complex lies along the reaction pathway, the charge-transfer complex acts as a real intermediate rather than a bystander in the addition reaction of the 2-nitropropane anion with the o-quinone derivative. A comparison of the observed rate constants with those predicted for the electron transfer from nitroalkane anions to o-quinones indicates that the addition reaction proceeds via electron transfer in the charge-transfer complex formed between nitroalkane anions and the o-quinones, followed by C-O adduct formation and subsequent cyclization to afford the 1,3-dioxole derivatives.

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.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 51166-71-3, you can contact me at any time and look forward to more communication. Recommanded Product: 2,6-Di-O-methyl-β-cyclodextrin.

Gas permeation properties of three highly permeable perfluorinated polymers (polyhexafluoropropylene (PHFP), amorphous Teflon AF2400, and polyperfluoro(2-methyl-2-ethyl-dioxole-1,3) (PPFMED)), which are promising materials for the dense thin layer of hollow fiber membranes for extracorporeal membrane oxygenation have been studied using nitrogen, oxygen, and carbon dioxide. Hemocompatibility of the polymeric films has also been investigated on whole blood from healthy donors. Gas permeation of the polymers increases in the order PHFP < PPFMEDD < AF2400, with PHFP alone having the permeability coefficients of the gases do not below those of polydimethylsiloxane applied as the selective layer of blood oxygenation membranes. Hemocompatibility of the polymers declines in the order PHFP > PPFMED > AF2400, with the most permeable polymer AF2400 exhibiting the worst hemocompatibility among the other polymers studied. Polyperfluoro(2-methyl-2-ethyl-dioxole-1,3) is shown to be the most appropriate polymer to fabricate hollow fiber membranes for blood oxygenation.

In the title compound, C(9)H(8)O(3), the dihedral angle between the mean planes of the benzene and dioxole rings is 1.4 (8)degrees, with the dioxole group in a slightly distorted envelope configuration with the flap C atom displaced by 0.0645 angstrom from the plane through the other four atoms. In the crystal, weak intermolecular C-H center dot center dot center dot O hydrogen-bond interactions link the molecules into chains propagating in [011]. The crystal packing exhibits weak pi-pi interactions as evidenced by the relatively short distances [3.801 (9) angstrom] between the centroids of adjacent benzene rings.
