Book excerpt: Targeted alpha therapy is an appealing method for the treatment of cancer as a complement to the current approaches. Astatine-211, with a half-life of 7.21 h, is considered as an exciting prospective candidate for this application. A pre-required condition is to fix in a stable way the radioactive isotope to the vector that is going to serve to recognize cells. This asks for a thorough knowledge of the chemical properties of astatine. Considering its position in the periodic table, it can exist under the form At- in coherence with the chemical properties of the other halogens, and also possesses a more metallic character that explains the existence of stable cationic species. The objective in this work is to identify the properties of different At species in aqueous solution. The predominance of the species At- in reducing acidic conditions was confirmed by means of a technique of electromobility. A first value of absolute mobility is then proposed. In more oxidizing conditions, the species At+ dominates. The reactivity of this species with the ions of the halogens series was studied/quantified. An exotic species IAtBr- was highlighted in particular thanks to the help of modeling tools. The peculiarity of the compound AtI to form halogen-type bonds was shown for the first time.

Download or read book At Astatine written by Hans K. Kugler and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astatine is - besides radon and francium - the only natural radioelement which only has short-Lived isotopes, thereby excluding experiments with . . weighable" amounts of the element. This implies that all available data on physics and chemistry of this element are 12 16 based on experiments on the tracer scale with 10- to 10- g - and this will also not change in future because no longer-Lived isotopes as yet known are to be expected. Due to the fact that the only isotope of At occurring in the natural decay series, 219At, results from the 0. 005% a-branching of 223Fr which itself is produced by the only 1. 38% a-branching of 227 Ac - a member of the 235U series - there is no chance to recover substantial amounts of 219At from natural sources for sCientific research of At. All studies, therefore, are being done with the isotopes 209At to 211At having half-lives in the few hours region and being obtained by irradiation of bismuth with a-particles via (a,xn) reactions or by proton irradiation of heavy elements via spallation reactions. The mostly used isotope is 7. 22 h 211At. The fast separation of the obtained At isotopes is no very difficult procedure and is either being done by wet adsorption-precipitation techniques or making use of its high volatility by destilling in air.

Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Chlorine, Bromine, Iodine and Astatine is a special edition that contains selected sections and addresses the needs of specialists in their respective fields. The text describes the general atomic properties of non-metals, particularly the halogens, as being the perfect series to study, both in physical and chemical terms. The book explains that the combination of the atomic properties implies excellent electronegativity values for the halogen atoms. The text also cites some behavior characteristics of halogens that are irregular, such as chlorine and bromine are similar but differ from fluorine on one side and iodine on the other. The book also compares the general methods of producing chlorine, bromine, or iodine by 1) oxidation of halide derivatives or 2) reduction of compounds of the halogens in positive oxidation states. The text then reviews the application of a complex valence theory that raises difficult questions about the bonding in halogen-oxygen molecules. The book also explains the biological behavior of astatine that accumulates in the liver or in the thyroid gland depending on the method of administration either as a radiocolloid or as a true solution. The book is suitable for molecular biologists and researchers, molecular chemists, and medical researchers.

Available in PDF, EPUB and Kindle. Book excerpt: The most complete resource in functional group chemistry Patai's Chemistry of Functional Groups is one of chemistry's landmark book series in organic chemistry. An indispensible resource for the organic chemist, this is the most comprehensive reference available in functional group chemistry. Founded in 1964 by the late Professor Saul Patai, the aim of Patai's Chemistry of Functional Groups is to cover all the aspects of the chemistry of an important functional group in each volume, with the emphasis not only on the functional group but on the whole molecule.
