Samarium(II) iodide mediated transformations of carbohydrate derived alkenyl iodides

D-ribonolactone derived acyclic alkenyl iodides were treated with samarium(II) iodide in THF/MeOH/HMPA at low temperature. Highly functionalized carbocycles are formed if the iodide is tethered to an allylic alcohol, an allylic acetate or an alpha, beta – unsaturated t-butyl ester. The chemoselectivity and diastereoselectively of these transformations vary with the Solvent system and with the reaction temperature. (C) 1997, Elsevier Science Ltd.

Thermodynamic analysis of production of high purity titanium by thermal decomposition of titanium iodide

High purity titanium was prepared by thermal decomposition of titanium iodide. The feasible synthetic route and optimum decompositon temperaure were obtained by thermodynamic analysis in the process of thermal decomposition of titanium iodide and nucleation growth theory. The temperature for the formation of titanium iodide is in the range of 800-900 K, at which a large amount of titanium iodide vapour can be obtained. The decomposition temperature of titanium iodide is in the range of 1 300-1 500 K, at which a favourable decomposition rate can be achieved. The experiment results show that the purity of the produced titanium is more than 99.995%.

Acyl iodides in organic synthesis: VI.* reactions with vinyl ethers

Reactions of acetyl iodide with butyl vinyl ether, 1,2-divinyloxyethane, phenyl vinyl ether, 1,4-divinyloxybenzene, and divinyl ether were studied. Vinyl ethers derived from aliphatic alcohols (butyl vinyl ether and 1,2-divinyloxyethane) react with acetyl iodide in a way similar to ethyl vinyl ether, i.e., with cleavage of both O-C-sp2 and Alk-O ether bonds. From butyl vinyl ether, a mixture of vinyl iodide, butyl acetate, vinyl acetate, and butyl iodide is formed, while 1,2-divinyloxyethane gives rise to vinyl iodide, vinyl acetate, and 2-iodoethyl acetate. The reaction of acetyl iodide with divinyl ether involves cleavage of only one O-C-sp2 bond, yielding vinyl acetate and vinyl iodide. In the reactions of acetyl iodide with phenyl vinyl ether and 1,4-divinyloxybenzene, only the O-C-Vin bond is cleaved, whereas the O-C-Ar bond remains intact.

A Rare Case of Iodide Mumps after Percutaneous Interventional Liver Transarterial Chemoembolization

Iodide-induced sialadenitis (iodide mumps) is a rare complication of iodide-containing contrast media administration. The phenomenon is, in fact, a form of aseptic sialadenitis and is characterized by acute swelling of the salivary glands. The cause of this condition is not yet entirely clear, but reports have been published in favor of iodine concentration in the salivary glands. In this article, we present the first ever case of iodide-induced sialadenitis reported in our country, which arose following a percutaneous transarterial liver chemoembolization procedure.

Effect of different iodide salts on ionic conductivity and structural and thermal behavior of rice-starch-based polymer electrolytes for dye-sensitized solar cell application

Biodegradable-based rice starch is used to prepare polymer electrolytes (PEs) using different iodide salts. Lithium iodide (LiI), ammonium iodide (NH4I), and sodium iodide (NaI) are used in this work. Polymer electrolytes are prepared using solution cast technique. The ionic conductivity of PEs is measured and temperature-dependent behavior of PEs studied. The polymer electrolyte system containing sodium iodide shows the highest ionic conductivity upon addition of 45 wt% sodium iodide. Fourier transform infrared (FTIR) results confirm complexation between polymer and salt. Thermal behavior of PEs is studied under thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The polymer electrolyte with 45 wt% of NaI is used to fabricate dye-sensitized solar cell (DSSC) and analyzed under Sun simulator.

Sodium/iodide symporter: physiopathological aspects and therapeutic perspectives

The existence of the natriuric/iodide symporter (NIS) represents a new view to understand the thyroid metabolism of iodide. Due to its cellular localisation on basolateral membrane, this transporter exerts an essential role in the biological functions of the thyroid, especially the capacity to accumulate iodide into the thyrocytes. Clinical perspectives of NIS activity modulation would ameliorate the diagnosis and the treatment of thyroid diseases by using radioisotopes transported by the NIS (131 iodide, 99m technetium, 188 rhenium). The study of the regulation pathways modulating the expression and the activity of the symporter NIS, would allow to understand pathogeny of benign or malignant diseases of the thyroid gland. The relative facility of the therapy management by 131 iodide and its good efficiency associated to the recent advance of NIS function also give an interesting perspective to the gene therapy treatment of the nonthyroid cancers despite existent methodological problems.

A novel fluorometric and colorimetric sensor for iodide determination using DNA-templated gold/silver nanoclusters

Determination of iodide ions has attracted considerable interest due to the importance and urgency. In the current work, we have developed a novel fluorescent and colorimetric platform for simple and selective detection of iodide ions based on the DNA-templated gold/silver nanoclusters (DNA-Au/Ag NCs). The detection system is based on the unique interaction between iodide ions and DNA-Au/Ag NCs, which shows an obvious fluorescence quenching with the addition of iodide ions and a good linear range from 0 to 10 mu mol/L for iodide ions. In the mean time, the detection system also exhibits an obvious color change from colorless transparent to purple red with the addition of iodide ions. Furthermore, the proposed system has been successfully applied for determination of iodide ions in real water samples.
