A flow injection analysis system was built with a liquid core waveguide spectrophotometric detector using an 80 cm Teflon AF-1600 capillary tube (2,2-bistrifluoromethyl-4,5-difluoro-1,3-dioxole/tetrafluoroethylene). The system was applied to determine nitrite ion in river water samples. The lower limit of detection for nitrite was 2.1 nmol dm(-3) (0.1 ng dm(-3) as NO2-) and the relative standard deviation of measurements was typically 0.56% (n=5) at 0.21 mu mol dm(-3).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 106-91-2. Quality Control of Oxiran-2-ylmethyl methacrylate.

Perfluoro(5-methylene-2,2-dimethyl-1,3-dioxolane) (1) was synthesized by utilizing a direct fluorination reaction. Compound 1 was an entirely novel monomer with difluoromethylene at position 5 on the dioxolane ring as an unprecedented polymerization site. It successfully polymerized with tetrafluoroethylene to afford copolymers, which had T-g values in the range of 60-90 degrees C. The content of monomer 1 in the obtained polymers was less than 20 mol%, which seemed insufficient for giving various unique properties to polymers. However, each polymer was expected to be a superior material because of their advanced thermal stability. Comparison with copolymers of 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole and tetrafluoroethylene is also discussed. (C) 2007 Elsevier B.V. All rights reserved.

Inhalation toxicity of Dioxole and Dioxolane compounds in the rat

Four chemicals (Dioxole 418, Dioxolane 418, Dioxolane 416 and Dioxolane 456) which are used as stabilizers in highresolution image were tested or both their acute and repeated inhalation toxicity in the rat using nose-only exposures. Acute studies determined the lethal concentrations following a single 4-hour exposure, repeated exposure inhalation studies determined the potency and target tissue(s) following 6-hour/day exposures, 5 days/week for 2 weeks. Each of the chemicals was at least mildly toxic acutely with approximate lethal concentrations of > 1,500 ppm for Dioxole 418, 1,300 ppm for Dioxolane 418, 1,700 ppm for Dioxolane 416, and 4,300 ppm for Dioxolane 456. No specific unusual clinical signs of response were seen in the rats exposed acutely. Repeated exposures with Dioxole 418 and Dioxolane 418 resulted in no evidence of toxicity with NOAEL’s being 440 and 500 ppm respectively (the highest concentrations tested). Repeated exposures to 250 ppm Dioxolane 456 were not tolerated with mortalities observed after exposure. Severe bone marrow hypoplasia along with reductions in platelet and neutrophil counts were observed at this concentration with less severe hemopoietic changes seen also at 10 and 51 ppm. The no-effect level for Dioxolane 456 was determined to be 10 ppm in female rats and I ppm in males. The same hemopoietic effects were seen with Dioxolane 416 at exposures of 53 ppm or greater in males but not in females exposed to 53 ppm Dioxolane 416. Hepatocellular hypertrophy and depression of serum alkaline phosphatase activity were seen in male rats exposed to 500 but not 53 ppm Dioxolane 416. Testicular degeneration was also seen in rats exposed to 500 ppm Dioxolane 416. The NOAEL was 5 ppm for the chemical.

Intramolecular Diels-Alder cycloadditions of cis-cyclohexadienediols derived enzymatically from (2-azidoethyl)benzene. Construction of highly functionalized bridged isoquinoline synthons

(3aR,7aS)-4-(2-Azidoethyl)-2,2-dimethyl-3a,7a-dihydrobenzo[1,3]dioxole (22) was converted in two steps to trienes 23 and 24, which upon heating underwent intramolecular Diels-Alder reactions to give mixtures of isomeric 11,11-dimethyl-5-oxo-10,12-dioxa-4-azatetracyclo[6.5.2.0(1.6).0(9,13)]pentadec-14-ene-7-carboxylates 25, 26 and 27, 28, respectively. These products were separated and identified. For comparison, intermolecular Diels-Alder cycloaddition of diene 22 with maleic anhydride was carried out. Products of this reaction, 1-(2-azidoethyl)-4,4-dimethyl-3,5,10-trioxatetracyclo[5.5.2.0(2,6).0(8,12)]tetradec-13-ene-9,11-diones (29 and 30) were converted to methyl ester analogues of 31 and 32 in a two-step sequence. The stereochemical outcome of these cycloadditions is discussed as well as their possible utilization in organic synthesis, especially in total synthesis of some alkaloids.

Molecular design of triarylamine dyes incorporating phenylene spacer and the influence of alkoxy substituent on the performance of dye-sensitized solar cells

Molecular design and understanding the structure-property relationship of pi-conjugated spacer play pivotal roles in realization of considerable enhancement performance of dye-sensitized solar cells (DSSCs). Three triphenylmaine dyes, namely MX11-13, have been designed and synthesized, which incorporate 2,2,6,6-tetramethylbenzol[,2-d:4,5-d’]bis[1,3]dioxole (TMBD), phenyl and 1,4-dipropoxybenzene (DPB) as pi-conjugated spacer, respectively. The effects of alkoxy substituent upon the photophysical, electro-chemical characteristics and performance of dye-sensitized solar cells are investigated. For a typical device, the MX13-based cell affords an overall power conversion efficiency (eta) of 7.02%, with short-circuit photocurrent density (J(SC)), open-circuit voltage (V(OC)) and fill factor (if) of 15.5 mA cm(-2), 697 mV and 0.65, respectively.

NMR characterization of penetrants in high permeability polymers

Spectra of xenon-129 sorbed into two high permeability polymers are reported. The polymers are the copolymer of tetrafluoroethylene and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole as well as poly(1-trimethylsilyl-1-propyne). At room temperature, the xenon-129 shifts are smaller than in conventional glassy polymers. The smaller xenon-129 shift indicates the presence of larger sorption sites in high permeability polymers relative to conventional polymers. The temperature dependence of solubility in these polymers is drastically different from the behavior in conventional polymers. There is a rapid exponential increase in solubility in high permeability polymers as temperature decreases corresponding to a large negative enthalpy change on sorption and it is this increase in solubility which leads to a large increase in shift with decreasing temperature. Pulse field gradient (PFG) determinations of the self-diffusion constant are made for xenon, propane, pentane and a decafluoropentane in the copolymer. Rapid diffusion is observed as well as a dependence of the apparent diffusion constant on the time scale of the PFG experiment. The translational mobility of smaller simpler moieties depends less on the time scale or equivalently, the length scale of observation in the PFG NMR experiment. For larger, more complex species, the interconnectedness of high free volume domains plays a role in reducing the apparent diffusion constant as the time of measurement increases.

Novel furfurylidene N-acylhydrazones derived from natural safrole: discovery of LASSBio-1215, a new potent antiplatelet prototype

We describe herein the discovery of (E)-N-methyl-N’-((5-nitrofuran-2-yl) methylene) benzo[d][1,3]dioxole-5-carbohydrazide (9e), named LASSBio-1215, as a novel antiplatelet agent belonging to the N-methyl-N-acylhydrazone class, which exert their antiaggregating actions on human and rabbit platelets induced by different agonists, through cyclooxygenase-1 (COX-1) or thromboxane synthase inhibition. This compound was elected after screening of a series of functionalized furyl N-acylhydrazone derivatives, synthesized from natural safrole 10. In vitro assays showed that compound 9e presents platelet-aggregating activity in rabbit platelet-rich plasma (PRP) induced by arachidonic acid (IC50 = 0.7 mu M) and collagen (IC50 = 4.5 mu M). Moreover, LASSBio-1215 also inhibited almost completely the second wave of adenosine diphosphate-induced platelet aggregation in human PRP, and this effect was correlated with their ability to block the production of pro-aggregating autacoid thromboxane A(2).
