Resumen

Abstract. Iodine is an essential trace element for all mammals and may also influence climate through new aerosol formation. Atmospheric bromine cycling is also important due to its well-known ozone depletion capabilities. Despite precipitation being the ultimate source of iodine in the terrestrial environment, the processes effecting its distribution, speciation and transport are relatively unknown. The aim of this study was to determine the effect of orographically induced precipitation on iodine concentrations in snow and also to quantify the inorganic and organic iodine and bromine species

Abstract. Sea ice is an integral part of the Earth's climate system because it affects planetary albedo, sea surface salinity, and the atmosphere-ocean exchange of reactive gases and aerosols. Bromine and iodine chemistry is active at polar sea ice margins with the occurrence of bromine explosions and the biological production of organo-iodine from sea ice algae. Satellite measurements demonstrate that concentrations of bromine oxide (BrO) and iodine oxide (IO) decrease over sea ice toward the Antarctic interior.

Resumen

Two highly sensitive spectrophotometric methods are proposed for the quantification of atenolol (ATN) in pure drug as well as in pharmaceutical formulations. The methods are based on the bromination reaction of ATN with a known excess of bromate-bromide mixture in acid medium followed by the determination of unreacted bromine. The residual bromine is determined by its reaction with excess iodide and the liberated iodine (I3?) is either measured at 360 nm (method A) or reacted with starch followed by the measurement of the starch-iodine chromogen at 570 nm (method B).

Resumen

Abstract A semimicro method for determination of iodine values of lipids is described. An accurately weighed smear of sample (10-20 mg) on a strip of ashless filter paper, 14 × 40 mm, is brominated with bromine vapors for about 5 min. Excess bromine adsorbed on the filter paper is allowed to sublime. Bromine absorbed by the sample is directly related to the degree of unsaturation. Paper with brominated sample is subjected to oxygen flask combustion in the presence of 2 mL 1M sodium hydroxide solution and 10 mL water as absorbing liquid. Bromide formed, which is equivalent to unsaturation, is d

Derivatives of 1,2,4-triazine-3-thione exhibit biological activity in a wide range. They have optoelectronic properties and can be used as synthons in synthesis of various pyridines by the Diels-Alder reaction. 1,2,4-Triazines are of the greatest interest, for organic synthesis in particular. In the present study we have established that the interaction of 3-propargylsulfanyl-5-phenyl-1,2,4-triazine, obtained by alkylation of 5-phenyl-2,3-dihydro-1,2,4-triazine-3-thione with 3-bromopropyne in acetone in the presence of triethylamine, with halogens leads to annelation of thiazole cycle.

The optical influence of mixing methylammonium lead chlorine (MAPbCl3) with iodine and bromine was studied in this work. The spin coating method deposited three layers of perovskites (MAPbCl3, MAPbCl2I, and MAPbCl2Br) on a layer of zinc oxide (ZnO). The zinc oxide solution was prepared by dissolving dehydrated zinc acetate [Zn(CH3COO)2, 2H2O]> 99.5% purity in ethanol to give a 0.5 M solution. The perovskite solutions were prepared using lead chloride (PbCl2), methylammonium chloride (MACl), methylammonium iodide (MAI), and methylammonium bromide (MABr).

Halonium ions, in which formally positively charged halogens (chlorine, bromine, and iodine) are equivalently attached to two carbon atoms through three-center bonds, are well established in the synthetic chemistry of organochlorides, bromides, and iodides.

However, it has not been clear whether fluorine can form a halonium ion in the same manner. We present chemical and theoretical evidence for the transient generation of a true symmetrical fluoroniu

Resumen

The influence of the reactor walls on combustion of gas mixtures containing halogenated hydrocarbons at atmospheric pressure has been studied experimentally. When the wall is contaminated with combustion products, the additional amounts of bromine or iodine that passed from it into the volume reduce the efficiency of combustion inhibition of hydrogen–air mixtures by bromine- and iodine-containing hydrocarbons (the effect was more pronounced for iodinated substances) and weakens the self-inhibition of the combustion of ethyl bromide in a mixture with air, leading to the expansion of the concent

Resumen

Abstract. The role of sea ice in the Earth climate system is still under debate, although it is known to influence albedo, ocean circulation, and atmosphere–ocean heat and gas exchange. Here we present a reconstruction of 1950 to 1998 AD sea ice in the Laptev Sea based on the Akademii Nauk ice core (Severnaya Zemlya, Russian Arctic). The chemistry of halogens bromine (Br) and iodine (I) is strongly active and influenced by sea ice dynamics, in terms of physical, chemical and biological process. Bromine reacts on the sea ice surface in autocatalyzing "bromine explosion" events, causing an enric

A new visible-light-induced methodology, termed as “bromine-iodine transformation activated living radical polymerization”, was successfully established to build a “bridge” between ATRP and iodine-mediated LRP techniques.

Abstract Selenium (1) and tellurium bis(trithiocarbonates) (2) were found to react with bromine and iodine to give the corresponding haloselenium (11) and halotellurium trithiocarbonates (7, 8). Reaction of 2 with excess of bromine give tribromotellurium trithiocarbonates (9).

Resumen

The chemistry of hypervalent halogen species has made enormous progress over the last few decades, and hypervalent iodine(III) compounds have become common reagents in nowadays organic synthesis. The related isoelectronic hypervalent bromine(III) species feature superior reactivity to the I(III) counterparts due to the higher oxidizing ability, stronger electrophilicity and better leaving group ability (nucleofugality) of the bromanyl moiety. However, the hypervalent bromine chemistry appears to be significantly less developed than that of the iodine(III) compounds. This notable imbalance appe

Resumen

AbstractChlorine is the most abundant halogen in sedimentary formation waters with concentrations from <100 to >250000 mg/l. Bromine is the second most abundant halogen at <1 mg/l to >6000 mg/l with iodine from <0.1 mg/l to >100 mg/l and fluorine from <0.1 mg/l to 30 mg/l. Chlorine and bromine show a strong systematic covariation suggesting that they are subject to the same controlling mechanisms. Fluorine only shows relatively high concentrations at elevated chlorine and bromine concentrations showing that fluorine, chlorine and bromine are possibly controlled by the same

Resumen

Abstract. Halogen chemistry in the polar regions occurs through the release of halogen elements from different sources. Bromine is primarily emitted from sea salt aerosols and other saline condensed phases associated with sea ice surfaces, while iodine is affected by the release of organic compounds from algae colonies living within the sea ice environment. Measurements of halogen species in polar snow samples are limited to a few sites although there is some evidence that they are related to sea ice extent. We examine here total bromine, iodine and sodium concentrations in a series of 2 m cor

Resumen

Biologically useful 7-azaindoles were synthesized by electrophilic cyclization of 3-alkynyl-N,N-dimethylpyridine-2-amines with molecular iodine. By this simple atom-economical approach under ambient reaction conditions, a library of interesting 3-iodo-7-azaindoles were synthesized in high yields. To synthesize the corresponding 3-bromo- and 3-chloro-7-azaindoles, an environmentally benign copper-mediated cyclization was employed, with inexpensive, nontoxic, and noncorrosive sodium chloride and sodium bromide as the sources of chlorine and bromine, respectively.

Resumen

This study investigates the structure of 21 table salts that were collected from different local markets in the Kurdistan region of Iraq. The major trace elements and iodine concentrations in tablesalt are analyzed through the X-ray fluorescence (XRF) technique and the titration method, respectively. The study shows that using XRF spectral analysis, the collected table salt samples are rich in chlorine, sodium, and contain a lower percentage of bromine, strontium, tin, tellurium, and iodine. Moreover, these samples have a high percentage of sulfur and sirconium, where the molybdenum is >0.2
