The radiation chemistry of the copolymer of tetrafluoroethylene and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (Teflon AF(R)) was investigated using gamma-irradiation under vacuum. Two types of resin were studied which differed in dioxole content; AF1600 65 mol% dioxole and AF2400 87 mol% dioxole. The cyclic fluoroplastic was found to undergo predominant main chain scission upon radiolysis, both above and below the glass transition temperature, which was characterised by a decrease in the glass transition temperature. FTIR analysis showed the formation of new carboxylate end groups as well as terminal unsaturation. Both CF . and CF2., radicals were identified using Electron Spin Resonance upon gamma-radiolysis and subsequent thermal annealing. The G-value for radical production at 77 K, G(R), was 1.6 for both resins. (C) 1998 Elsevier Science Ltd. All rights reserved.

A new decarboxylative perfluoroalkylation of vinyl bromides has been developed. The use of copper(I) trifluoroacetate complex (phen)Cu(O2CCF3) (1) and perfluorocarboxylate complexes [(phen)(2)Cu](O2CRF) (2; R-F=C2F5, n-C3F7, n-C4F9, n-C5F11) as reagents allows for the efficient synthesis of trifluoromethylated and perfluoroalkylated olefins, respectively. Vinyl bromides comprising a range of functionalities (e.g., methoxy, ester, nitrile, nitro, trifluoromethyl, chloride, and benzo[d][1,3]dioxole) were successfully accommodated. The decarboxylative trifluoromethylation and perfluoroalkylation reactions also proceeded with retention of the double-bond stereochemistry of alkenes after the reaction was completed.

Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout, creation and manufacturing process of chemical products and materials. 91526-18-0, Name is 4-(Hydroxymethyl)-5-methyl-1,3-dioxol-2-one, SMILES is CC1=C(CO)OC(=O)O1, belongs to dioxole compound.

Sorption of a series of gases; perfluorocarbon vapors (CF4, C2F6, and C3F8) and their hydrocarbon analogues in poly(dimethylsiloxane) [PDMS], poly(1-trimethylsilyl-1-propyne) [PTMSP], and two random copolymers of tetrafluoroethylene [TFE] and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole [BDD] are reported as a function of penetrant pressure at 35 degrees C. Sorption isotherms for all penetrants in rubbery PDMS are linear or slightly convex to the pressure axis, while those in the glassy polymers are concave and are well described by the dual mode model. Fluorocarbon sorption levels are lower than sorption levels of their hydrocarbon analogues in the hydrocarbon-based PDMS and PTMSP matrixes while the reverse is true in the fluorinated TFE/BDD copolymers. Exceptionally low fluorocarbon solubilities in PDMS are ascribed to poor penetrant/polymer energetic interactions.

A divergent synthesis of 10 icetexane natural products based on a proposed biogenetic cationic ring expansion of a reduced carnosic acid derivative is described. Of these icetexanes, (+)-salvicanol, (-)-cyclocoulterone, (-)-coulterone, (-)-obtusinone D, and (-)-obtusinone E have been synthesized for the first time. In addition, the hypothesis for the non-enzymatic biogenesis of benzo[1,3]dioxole natural products has been experimentally investigated. Additional experimental evidence for the abiotic formation of the methylenedioxy unit is provided, as photolysis of the quinone (+)-komaroviquinone resulted in the formation of the [1,3]dioxole-containing natural product (-)-cyclocoulterone and (+)-komarovispirone.

Para-hexaphenylene (p-6P) molecules exhibit a characteristic photoinduced reaction (bleaching) resulting in a decrease in luminescence intensity upon UV light exposure, which could render the technological use of the nanofibers problematic. In order to investigate the photoinduced reaction in nanofibers, optical bleaching experiments have been performed by irradiating both pristine and coated nanofibers with UV light. Oxide coating materials (SiO(x) and Al(2)O(3)) were applied onto p-6P nanofibers. These treatments caused a reduction in the bleaching reaction but in addition, the nanofiber luminescence spectrum was significantly altered. It was observed that some polymer coatings [a statistical copolymer of tetrafluoroethylene and 2,2-bis-trifluoromethyl-4,5-difluoro-1,3-dioxole, P(TFE-PDD), and poly(methyl methacrylate), PMMA] do not interfere with the luminescence spectrum from the p-6P but are not effective in stopping the bleaching. Bilayer coatings with first a polymer material, which should work as a protection layer to avoid modifications of the p-6P luminescence spectrum, and second an oxide layer used as oxygen blocker were tested and it was found that a particular bilayer polymer/oxide combination results in a significant reduction in bleaching without affecting significantly the emission spectrum from the nanofibers.

Phenyleneethynylene-based conjugated copolymers using benzo[1,2-d:4,5-d’]bis[1,3]dioxole (BDO) in the repeating unit are reported. The electronic structure of the BDO unit imparts a localized HOMO topology while the LUMO is delocalized over the polymer backbone, so that the lowest optical absorption band of the polymer has considerable intramolecular charge transfer character. This contrasts with published donor-acceptor polymers with localized LUMO and delocalized HOMO. The very large Stokes shifts of the monomers, which are due to the small oscillator strength of the lowest optical transition, are largely retained in the polymers as a result of covalently constrained dihedral angles in the substituents (not the backbone), as predicted/explained by calculations.

Molecular behavior of the building block ([2-(1,3-dithiole-2-ylidene)-1,3-dithiole] =tetrathiafulvalene (TTF)} of organic superconductors have been investigated along with its three derivatives, namely, {[2-(1,3-dioxole-2-ylidene)-1,3-dioxole] tetraoxafulvalene (TOF)}; [2,2]-bi-[[1,3] oxathiolylidene]=Der I and 2-(3H-Furan-2-ylidene)-[1,3] oxathiole=Der II. The properties of the molecules such as molecular geometries, frontier MOs and vibrational spectra have been investigated by using DFT method at the B3LYP level employing 6-311++G(d,p) basis set. The geometrical parameters and atomic charges on various atomic sites of the TTF, TOF, Ders land II suggest extended conjugation in these systems. The present calculations lead to the reassignments for of some of the fundamentals and new interpretations for some of the observed IR and Raman frequencies. One of the two modes involved in the Fermi resonance giving rise to the doublet 1555 and 1564 cm(-1) needed to be revised and another doublet 3083 and 3108 cm(-1) could be interpreted as a Fermi resonance doublet. Out of the two nu(C=C) modes under the a(1) species, the lower frequency mode is assigned to the nu(C=C) of the ring and the higher one to the nu(C=C) of the central C=C bond contrary to the assignment reported in literature. The conducting properties of these molecules depend mainly on this mode. (C) 2012 Elsevier B.V. All rights reserved.

The title compound, C18H20O4, is structurally similar to podophyllotoxin. It contains a fused dioxole and phenyl ring system and an unfused phenyl ring which are almost perpendicular to each other. However, this compound lacks the cyclohexyl and lactone rings which are present in podophyllotoxin. In addition, the unfused phenyl ring in podophyllotoxin contains three methoxy groups in the para and meta positions, whereas the title compound contains only an ethoxy group in the para position.

In spite of early reports by Birch, we demonstrated that treatment of benzodioxoles with sodium in ammonia in the presence of methanol almost quantitatively yields the corresponding dihydro compounds. Despite their poor stability these compounds are synthetically useful. Treatment of 5-isobutyl-4,7-dihydrobenzo[1,3]dioxole with bromotrimethylsilane gives 6-hydroxy-3-isobutylcyclohex-2-enone in 80% yield. Treatment of 4,7-dihydrobenzo[1,3]dioxole with potassium in liquid ammonia in the presence of iron(III) chloride leads to 3a,4-dihydrobenzo[1,3]dioxole in high yield..
