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.

The carbonylation of methyl iodide and methanol to methyl acetate catalysed by palladium and platinum iodides

Paladium(II) salts catalyse the carbonylation of methyl iodide in methanol to methyl acetate (5 atm CO, 140 degrees C) in the presence of a large excess of iodide, even without amine or phosphine co-ligands; platinum(II) salts show similar reactions but are a little less effective.

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%.

INHIBITION OF IODIDE TRANSPORT IN RAT-THYROID CELLS USING N-SUBSTITUTED ANTHRANILIC ACID-DERIVATIVES

The purpose of this study was to test the effects of chloride channel blockers on iodide uptake in thyroid cells, in the hope of eventually using these blockers to identify and isolate a putative iodide transporter, The chloride channel blockers used in this report are derivatives of N-substituted anthranilic acid and were synthesized using published procedures, For these studies FRTL-5 cells, a line of continuous-growing rat thyroid cells, were used as a model system to study effects on iodide transport. In these cells, there are at least two ways for transmembrane iodide movements, a sodium-dependent influx step and a proposed channel that normally mediates iodide efflux, Two derivatives studied decreased iodide accumulation in FRTL-5 cells, but were found also to lower intracellular pH and ATP levels, To simplify interpretation of the effect of the drugs on iodide transport, we extended the studies using plasma membrane vesicles made from pig thyroid, Iodide entry in these vesicles depended on a sodium gradient and was independent of ATP levels, Iodide transport in plasma membrane vesicles and FRTL-5 cells was measured at 30 sec when the uptake was nearly linear and therefore likely to reflect iodide entry, The uptake was measured using three concentrations of iodide and three of drug. Kinetic analysis of the data described a competitive inhibition by the drugs with a K-i of approximately 250 mu M. In summary, N-substituted anthranilic acid derivatives reversibly inhibit iodide entry in FRTL-5 cells and pig plasma membrane vesicles, Because of their ease of synthesis and modification, these derivatives are potentially useful probes for isolation of the NaI symporter in thyroid.

Colorimetric sensing of iodide based on triazole-acetamide functionalized gold nanoparticles

We have modified gold nanoparticles (AuNPs) with triazole acetamide to obtain a material for the sensitive and selective colorimetric determination of iodide. The functionalized AuNPs were prepared by a reductive single chemical step using a Cu(I)-catalyzed click reaction. The presence of iodide ions induces the aggregation of these AuNPs and results in a color change from wine-red to purple. The iodide-induced aggregation can be detected visually with bare eyes, but also by photometry. The detection limit is as low as 15 nM. The method displays excellent selectivity for iodide over other anions due to the selective interaction with the amido groups of the triazole. The method was applied to the determination of iodide in spiked lake waters.

Determination of iodide in common salts consumed in Turkey by isotope dilution analysis

Iodide traces in common salts consumed in Turkey have been determined by isotope dilution analysis. Iodide was precipitated by stoichiometric amount of AgNO3. Iodide-131 was used as tracer. Electrophoresis was performed to separate (AgI)-I-131 from excess I-131(-). Zone of (AgI)-I-131 was cut Off electrophoresis paper and counted with a NaI(Tl) scintillation counter. Count rates were plotted versus added KI concentrations. Unknown iodide amounts were found by using these linear plots. Iodide concentrations found in analyzed salts were 9-58 mu g/g.

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.

Solvent-Free, Microwave-Assisted Conversion of Tosylates into Iodides

A highly efficient method for the conversion of primary tosylates into the corresponding iodides is outlined. The method involves heating a neat mixture of the tosylate and solid sodium iodide in a microwave cavity. Reaction times are short, usually about 60 minutes, delivering high yields. This procedure is especially useful for the in situ generation of volatile primary iodides, and for most of the primary iodides, the crude product is sufficiently pure.

Impact of potassium iodide on thyroidectomy for Graves’ disease: Implications for safety and operative difficulty

Background. Potassium iodide often is prescribed prior to thyroidectomy for Graves’ disease, but the effect of potassium iodide on the ease and safety of thyroidectomy for Graves’ is largely unknown. Methods. We conducted a prospective, cohort study of patients with Graves’ disease undergoing thyroidectomy. For the first 8 months, no patients received potassium iodide; for the next 8 months, potassium iodide was added to the preoperative protocol for all patients. Outcomes included operative difficulty (based on the Thyroidectomy Difficulty Scale) and complications. Results. We included a total of 31 patients in the no potassium iodide group and 28 in the potassium iodide group. According to the Thyroidectomy Difficulty Scale, gland vascularity decreased in the potassium iodide group (mean score 2.6 vs 3.3, P = .04), but there were no differences in friability, fibrosis, or size of the thyroid or in overall difficulty of operation (P = not significant for all). Despite similar operative difficulty, patients prescribed potassium iodide were less likely to experience transient hypoparathyroidism (7% vs 26%, P = .018) and transient hoarseness (0% vs 16%, P = .009) compared with the no potassium iodide group. Conclusion. Potassium iodide administration decreases gland vascularity, but does not change the overall difficulty of thyroidectomy. Preoperative use of potassium iodide solution was, however, associated with less transient hypoparathyroidism and transient hoarseness, suggesting that potassium iodide improves the safety of thyroidectomy for Graves’ disease.
