[N Petragnani] -- Until about thirty years ago, tellurium, the fourth of the oxygen family of the periodic table, was practically unknown in organic chemistry books. The many classes of organotellurium compounds.

Zeni and co-workers developed a method for the synthesis of several functionalized alkynyl tellurides from the reaction of aryl, vinyl and alkynyl tellurides with alkynyl iodides catalyzed by copper(I).9 The new organotellurium compounds produce antidepressive-like activ-ity.

Organoselenium shows incredible promise in medicine, particularly cancer therapy. This book discusses organoselenium chemistry and biology in the context of its therapeutic potential, taking the reader through synthetic techniques, bioactivity and therapeutic applications. Divided into three sections, the first section describes synthetic advances in bioactive selenium compounds.

Detelluration of organotellurium compounds can be carried out with the formation of new C C bonds (carbodetelluration) or by replacement of the tellurium moiety by other functionalities such as halogens, methoxy groups or hydrogen. Carbodetelluration of diaryltellurium dichlorides 48 and aryltellurium trichlorides with Raney-nickel in an appropriate solvent constitutes a useful.

Organotellurium chemistry in chemistry describes the synthesis and properties of chemical compounds containing a carbon to tellurium chemical bond. Organotellurium chemistry was developed in the wake of organoselenium chemistry and, though sharing the same group in the periodic table, their chemistries are very different given the inversion of polarity in the.

A range of novel organotellurium compounds with an amino group ortho to the tellurium atom (i.e. ArTeBr 3 and Ar 2 Te, where Ar = 2-NH R C 6 H 3; R = CH 3, Br, NO 2) have been prepared by a convenient new route involving reaction of the corresponding 2-aminoarylmercury chloride with tellurium ion of ArTeBr 3 gave the compounds.

Herein we describe the results on the synthesis and the evaluation of the antioxidant activity of several organochalcogen-containing chrysin derivatives (Se and Te). The semi-synthetic compounds were easily synthesized in good to excellent yields by the reaction of 7-(2-bromoethoxy)-chrysin with nucleophilic.

(21) and Haiduc et. (22) The first organotellurium compound, Dimethyl telluride was prepared by Wohler (23) as early as in year The work on the synthesis of organotellurium compounds was later on picked up by Lederer (24) in year The various synthetic. Ammonium trichloro[1,2-ethanediolato-O,O']-tellurate (AS) is the most important synthetic Te compound from the standpoint of its biological activity.

It is a potent immunomodulator with a variety of potential therapeutic applications and antitumoral action in several preclinical and clinical studies.

Synthetic methods have been developed to prepare novel 1,3-benzotellurazoles carrying acylamino and arylamino moieties in position 2, in order to investigate their propensity to self-assemble to supramolecular structures.

The targeted compounds were obtained in yields ranging from 44% to 67%, by reacting bis(2-aminophenyl) ditelluride with acyl- and aryl.

Interests: synthesis and reactivity of organosulfur, organoselenium and organotellurium compounds, also mediated by organosilanes; study of their properties as new antioxidants and enzyme modulators; synthesis and functionalization of heterocyclic compounds.

The review summarizes the results of studies in the field of development of efficient proceduresfor the synthesis of dialkyl chalcogenides, dialkyl dichalcogenides, vinyl and ethynyl chalcogenides, andselenium- tellurium- and silicon-containing heterocyclic compounds on the basis of elemental seleniumand tellurium.

Abstract Although diethyl dielluide was first obtained about years ago,1 the aliphatic ditelluides have been relatively little studied. This is party due to the extremely repulsive odors of the lowest members of the series, but also to the fact that the known methods of synthesis are not practical for the preparation of large amounts of pure materials.2 Fo example, din-butyl.

The ability to endure tellurium–metal exchange with retention of the double bond configuration, allowing the formation of new carbon–carbon bonds in a very selective way, makes vinylic tellurides a promising class of compounds in organic synthesis.[] For the preparation of Z-vinylic tellurides,[] the most convenient and widely used method is the hydrotelluration of .Ammonium trichloro[1,2-ethanediolato-O,O′]-tellurate (AS) is the most important synthetic Te compound from the standpoint of its biological is a potent immunomodulator with a variety of potential therapeutic applications and antitumoral action in several preclinical and clinical studies.
