Synergistic Copper-Catalyzed Reductive.Aminocarbonylation of Alkyl Iodides with Nitroarenes

We have developed a Cu-catalyzed reductive aminocarbonylation of alkyl iodides using nitroarenes as the nitrogen source. The reaction proceeds with a single copper catalyst playing dual roles of synergistically mediating both carbonylation of alkyl iodides and reduction of nitroarenes, providing acyl iodides and anilines as possible reactive intermediates that then do amide coupling spontaneously. A diverse of alkyl iodides with nitroarenes range of secondary N-aryl alkylamides are accessible from a variety of primary, secondary, and tertiary alkyl iodides using this method.

Flow-injection determination of iodide with a silver electrode

A procedure is developed for the flow-injection determination of iodide using a modified silver electrode; it extends the analytical range of iodide by an order of magnitude as compared to potentiometric determination using an iodide-selective electrode with a polycrystalline membrane. The detection limit is 7 mu g/L. The procedure was used to determine iodide in natural mineral waters and model solutions. The throughput was 20-25 samples/h.

New iodide-based molten salt systems for high temperature molten salt batteries

Novel multi-component molten salt systems containing iodides, LiF-LiBr-Lil, LiF-NaBr-Lil, and LiF-LiCl-LiBr-Lil, were investigated for use as electrolytes in high temperature molten salt batteries to improve the discharge rate-capability. The iodide-based molten salts showed higher ionic conductivity (similar to 3 S cm(-1) at 500 degrees C) than conventional LiCl-KCl, and had low enough melting points (below 400 degrees C that can be used in practical high temperature molten salt batteries. The iodide-based salts showed instability at temperatures higher than 280 degrees C in dried air. The decomposition mechanism of iodide-based molten salts was discussed, and it was found that elimination of oxygen from the environment is effective to stabilize the iodide-based molten salts at high temperatures.

Iodine assimilation by marine diatoms and other phytoplankton in nitrate-replete conditions

Several marine phytoplankton species, primarily diatoms, were examined for the accumulation of iodide (10 species) and iodate (9 species) using radioactive iodine-125 in f/2 artificial seawater, a nitrate-enriched medium. Iodide accumulation ( net uptake) rates were variable, and diatoms exhibited the highest rates. Emiliania huxleyi and Synechococcus sp. did not accumulate iodide. Accumulation rates ranged from 0 to 1.7 fmol cell(-1) d(-1). The diatom Porosira glacialis accumulated the greatest amount of iodide and was used to determine efflux rates of iodide. Iodide efflux was characterized by two distinct phases of iodide release: an initial rapid release rate of 10 amol cell(-1) min(-1) from the free space and a subsequent cellular release rate of 0.13 amol cell(-1) min(-1), which corresponds to a daily cellular release rate of 0.19 fmol cell(-1) d(-1). Accumulation of iodate ranged from 0 to 19 amol cell(-1) d(-1), with P. glacialis displaying the highest rate. Emiliania, Synechococcus, and Chaetoceros did not show significant iodate accumulation. Iodide is the preferred chemical species of iodine for uptake under nitrate-replete conditions: iodide accumulation rates ranged from 3 to 90 times larger than those for iodate for the species studied. If the iodate accumulated is tightly coupled to its reduction to iodide, the accumulation rates suggest that phytoplankton-mediated iodate reduction is not environmentally significant. If diatoms can reduce iodate to iodide, their overall contribution to surface-water iodide, while living, would be further reduced because of their ability to reassimilate released iodide.

INHIBITION OF THYROCYTE IODIDE UPTAKE BY H(+)K(+)ATPASE INHIBITOR, TIMOPRAZOLE

The inhibitory effect of timoprazole on iodide uptake by cultured thyrocytes was observed using FRTL-5 cells. The inhibition was noticed to be dose dependent and was eliminated completely by rinsing. Timoprazole pretreated with acid had inhibitory effects, but [H-3] leucine incorporation experiments indicated that acidified timoprazole inhibited protein synthesis to some degree. In addition, TSH-induced cAMP production was also inhibited by acidified timoprazole. Timoprazole pretreated in a neutral solution did not have any cytotoxic effects on TSH-induced cAMP production or protein synthesis at concentrations less than 1000 mu M, suggesting that timoprazole by itself has specific effects on iodide uptake. The absence of any direct interaction of the drug with iodide was confirmed by separation of timoprazole and iodide on a C-18 Sep-Pak column. It is concluded that timoprazole by itself could inhibit iodide transport through the thyroid cell membrane. This may provide a useful system in further investigating the mechanism of iodide transport.
