Effects of Iodine and Iodine-Containing Compounds on Thyroid Function

Medical Clinics of North America, 1985
This article deals with iodine metabolism and the consequences of iodine deficiency and iodine excess. The mechanisms underlying the clinical presentation of these two conditions as well as the clinical implications, both diagnostic and therapeutic, are discussed.

The I=X (X=O,N,C) double bond in hypervalent iodine compounds: is it real?

Angewandte Chemie, 2014
IX (X=O, N, C) bonding was analyzed in the related hypervalent iodine compounds based on the adaptive natural density partitioning (AdNDP) approach. The results confirm the presence of a I→X σ dative bond, as opposed to the widely used IX notation.

Iodine Compounds in the Atmosphere

2005
The current understanding of iodine sources in the atmosphere, the abundance of atmospheric iodine compounds and their chemistry are reviewed. Besides CH3I, several other organic iodine compounds of biological origin, such as CH2I2, CH2ClI and C3H7I have been detected in ocean water. Due to their low solubility the water can become super-saturated with

Ferrate Oxidation of Phenolic Compounds in Iodine Containing Water: Control of Iodinated Aromatic Products.

Environmental Science and Technology, 2019
Highly toxic iodinated products would form in oxidation and disinfection of iodine containing water. Variation of iodinated aromatic products in ferrate [Fe(VI)] oxidation of phenolic compounds [phenol, bisphenol A (BPA), and p-hydroxybenzoic acid (p-HBA)

A New Iodine Compound for Cholecystography

Radiology, 1927
THE extensive use of sodium tetrabromphenolphthalein and sodium tetraiodophenolphthalein in cholecystography, since they were first introduced by Graham and his associates, has shown that these two compounds will serve efficiently. Intravenous administration of these drugs for cholecystography has the advantage of assuring that a specified dose has ...

Employing exchange reactions involving hypervalent iodine compounds for the direct synthesis of azide-containing linear and branched polymers

, 2014
A method for the preparation of azide-containing linear and branched polymers was developed that takes advantage of the efficient exchange of the acetoxy “ligands” in (diacetoxyiodo)benzene PhI(O2CCH3)2 (Ph = phenyl) with azides, for instance in the ...

Generation of Aryl Radicals through Reduction of Hypervalent Iodine(III) Compounds with TEMPONa: Radical Alkene Oxyarylation.

Chemistry, 2016
A novel method for selective generation of aryl radicals from diaryliodonium salts and iodanylidene malonates with sodium 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPONa) as a single-electron transfer (SET) reducing reagent is described. In the presence of
