Selenium– and tellurium–nitrogen reagents

Abstract

<jats:title>Abstract</jats:title> <jats:p>The reactivity of the chalcogen–nitrogen bond toward main-group element or transition-metal halides, as well as electrophilic and nucleophilic reagents, is the source of a variety of applications of Se–N and Te–N compounds in both inorganic or organic chemistry. The thermal lability of Se–N compounds also engenders useful transformations including the formation of radicals via homolytic Se–N bond cleavage. These aspects of Se–N and Te–N chemistry will be illustrated with examples from the reactions of the binary selenium nitride Se<jats:sub>4</jats:sub>N<jats:sub>4</jats:sub>, selenium–nitrogen halides [N(SeCl<jats:italic><jats:sub>n</jats:sub></jats:italic>)<jats:sub>2</jats:sub>]<jats:sup>+</jats:sup> (<jats:italic>n</jats:italic> = 1, 2), the synthons E(NSO)<jats:sub>2</jats:sub> (E = Se, Te), chalcogen–nitrogen–silicon reagents, chalcogen(IV) diimides RN=E=NR, the triimidotellurite dianion [Te(N<jats:sup>t</jats:sup>Bu)<jats:sub>3</jats:sub>]<jats:sup>2−</jats:sup>, chalcogen(II) amides and diamides E(NR<jats:sub>2</jats:sub>)<jats:sub>2</jats:sub> (E = Se, Te; R = alkyl, SiMe<jats:sub>3</jats:sub>), and heterocyclic systems.</jats:p>

A new organotellurium compounds based on camphor, aniline and p-toluidine: preparation, characterization and theoretical study

“…In recent years, there has been great interest in studying organo-tellurium compounds containing azomethane group due to the high stability and various applications of these compounds [3,4]. The applications of organotellurium compounds have been reported in several fields [4][5][6][7][8]. Past research reported using organotellurium compounds as antioxidant agents [5,9,10], polymerization catalysts [11][12][13], antitumor and pharmaceutical agents [5,14,15], organic superconductors [3,7], synthetic intermediate [4], and ligands with many transition metal ions [3,16,17].…”
