Acyl Iodides in Organic Synthesis. Reaction of Acyl Iodides with Triphenylethoxy-and Triphenylhydroxysilane

The reaction of triphenylethoxysilane with acetyl or benzoyl iodide led to the formation of triphenyliodosilane and ethyl ester of the corresponding carboxylic acid. Triphenyliodosilane formed also in the reaction of triphenylsilanol with benzoyl iodide. These reactions comprise the new simplest method of preparation of the triphenyliodosilane (yield over 60%). The reaction product of triphenylhydroxysilane and acetyl iodide is triphenylacetoxysilane. The reactions of the studied acyl iodides with triphenylhydroxysilane is the first example of different regioselectivity of acetyl iodide and benzoyl iodide in reactions with organic and organoelemental compounds.

Preoperative Administration of Excess Iodide Increases Thyroid Volume of Patients with Graves’ Disease

Preoperative excess iodide administration for patients with Graves’ disease has been widely adopted by surgeons to perform surgery safely, because it decreases blood flow in the thyroid. However, surgeons often encounter the enlargement of thyroid volume after iodide administration, which makes surgery even more difficult. In this study, we retrospectively investigated the change in thyroid volume in Graves’ disease that was evaluated on ultrasonography between before and after iodide administration. Eighty-nine patients who received iodide administered (KI(+) patients) and 24 ill whom iodide was not administrated (KI(-) patients) before surgery for Graves’ disease were enrolled in the study. The level of free T4 (FT4) significantly decreased and that of thyroid stimulating hormone (TSH) significantly increased after iodide administration. Average thyroid volume also significantly increased for KI(+) patients after iodide administration and 17% of these patients showed a 30% or more increase in thyroid volume. In KI(-) patients who were preoperatively treated only by anti-thyroid drugs, thyroid volume did not change before surgery. Preoperative TSH levels remained below measurement sensitivity in 37 of KI(+) patients, but the average thyroid volume also significantly increased after iodide administration. These findings suggest that thyroid volume in Graves’ disease call increase with iodide administration not only due to TSH stimulation but also due to reasons other than TSH. Surgeons should be careful when preoperatively iodide administering to patients with Graves’ disease, especially when the goiter is large.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 450412-29-0, in my other articles.

ATOMIC-FORCE MICROSCOPY OF LEAD IODIDE CRYSTAL-SURFACES

Atomic force microscopy (AFM) was used to characterize the surface of lead iodide crystals. The high vapor pressure of lead iodide prohibits the use of traditional high resolution surface study techniques that require high vacuum conditions. AFM was used to image numerous insulating surfaces in various ambients, with very little sample preparation techniques needed. Freshly cleaved and modified surfaces, including, chemical and vacuum etched, and air aged surfaces, were examined. Both intrinsic and induced defects were imaged with high resolution. The results were compared to a similar AFM study of mercuric iodide crystal surfaces and it was found that, at ambient conditions, lead iodide is significantly more stable than mercuric iodide.

Radiopaque poly(2-hydroxyethyl methacrylate) particles containing silver iodide complexes tested on cell culture

Silver iodide complexes have been used as an effective radiopacifying agent to prepare radiopaque poly(2-hydroxyethyl methacrylate) (poly(HEMA)) particles. Incorporation of silver iodide complexes inside the poly(HEMA) particles was achieved by first swelling particles in potassium iodide solution and precipitating the silver iodide complexes using a 30 wt% solution of silver nitrate. The dry particles contained 15 wt% of silver iodide complexes. Particles were easily monitored using a standard imaging technique based on X-ray absorption. Toxicity of the particles has been determined in in vitro experiments on a cell culture. As no inhibition of growth of cells surrounding the particles was observed, they can be considered non-toxic.

THE VOLATILIZATION OF IODINE SPECIES OVER DILUTE IODIDE SOLUTIONS

The volatility of iodine above dilute CsI solutions has been investigated experimentally. The partitioning of iodine between air and solutions prepared with iodide was found to increase with decreasing pH and iodide concentration. Aqueous to gaseous partition coefficients ranging from 3 x 10(3) to 10(7) were observed indicating that only a very small fraction of the iodide was oxidized to volatile forms. It was concluded that under these very dilute conditions, the rate of iodide oxidation was proportional to the square root of the iodide concentration; the rate also depended on pH under acidic conditions but not under basic conditions.

Molten and solid metal-iodide-doped trialkylsulphonium iodides and polyiodides as electrolytes in dye-sensitized nanocrystalline solar cells

The conductivity and solar cell performance of metal-iodide-doped trialkylsulphonium iodides and polyiodides have been investigated as electrolytes in dye-sensitized nanocrystalline solar cells (DNSCs). Nine different metal-iodide-containing (R2R’S)l with additional iodine provided overall solar-to-electric energy conversion efficiencies of over 2%, while used as electrolytes in DNSCs in simulated AM 1.5 solar light at the light intensity of 100 W m(-2). The highest overall conversion efficiency, 3.1%, was achieved by using the electrolyte (BU2MeS)I:AgI:I-2 in the proportions (1:0.03:0.05). The effects from 4-tert-butylpyridine treatment of the electrodes were studied. The effects of metal-iodide doping were also investigated with respect to speciation in the electrolytes and potential influence on electrochemical conductivity. (C) 2004 Elsevier B.V.

Influence of Different Electrolytes on the Reaction Mechanism of a Triiodide/Iodide Redox Couple on the Platinized FTO Glass Electrode in Dye-Sensitized Solar Cells

The reaction mechanisms of a triiodide/iodide redox Couple at the platinized FFO glass electrode/electrolyte interface with different electrolytes were Studied by cyclic voltammetry, steady polarization Curve, and chronocoulometric methods. It was found that the reaction process of the triiodide/iodide redox couple in electrolytes without nitrogenous heterocyclic additives was controlled by adsorption, and different iodide concentrations Could affect the reaction mechanism of the triiodide/iodide redox couple oil the platinized FTO glass electrode by changing the adsorption characteristic of iodide (triiodide). After nitrogenous heterocyclic additives were added into the electrolytes, the reaction process was controlled by a diffusion process. The nitrogenous heterocyclic additives can absorb on the electrode and change the reaction mechanism of the triiodide/iodide redox Couple by forming complex compounds with triiodide. The radius of the redox active species in the electrolyte with nitrogenous heterocyclic additives was big-er than that in electrolytes without nitrogenous heterocyclic additives.

Electrochemical quartz crystal microbalance study of adsorption of iodide on highly ordered Au(111)

The adsorption process of iodide on a highly ordered Au(111) electrode has been investigated using an electrochemical quartz crystal microbalance. Considering that the change of electric charge Delta Q is due to the adsorption or desorption of iodide ions on the surface, but the change of electrode mass Delta W is due to the adsorption or desorption of iodide ions and water molecules on the surface, the surface concentration of iodide ions and the change of surface excess of water on the Au(111) surface have been determined quantitatively. The coverages of Au(111) with iodide as a function of the electrode potential were quite consistent with those estimated from the scanning tunneling microscope image or using surface X-ray scattering. It was found that the surface excess of water changed with electrode potential during the adsorption of iodide on Au(111), showing a maximum around -0.20 V.
