Green Chemistry with Selenium Reagents: Development of Efficient Catalytic Reactions

TL;DR: A growing number of organopnictogen redox catalytic methods have emerged, especially within the past 10 years, that leverage the plentiful reversible two-electron redox chemistry within Group 15 as mentioned in this paper.

TL;DR: The use of selenating reagents has often been limited by a generally bad reputation surrounding selenium toxicity and its potential impact on the environment as discussed by the authors, however, some aspects that will encourage the reader to discover an unexpected "green side" to this element and the chemistry connected with its organic derivatives.

TL;DR: In this review the survey of developments pertaining to the designing of such complexes, and their uses as catalysts for various organic reactions has been presented with critical analysis of present status of the subject.

TL;DR: Synthetic applications of the oxidation reactions mediated by selenium(IV) oxide, areneseleninic acids, their anhydrides, selenides, diselenides, benzisoselenazol-3(2H)-ones and other less often used other organoselenium compounds are devoted.

TL;DR: Ene-chlorination of olefins by N-chlorosuccinimide is catalyzed by phenylselenenyl chloride and this reaction demonstrates the catalytic conversion of C-H bonds into more reactive C-Cl bonds.

TL;DR: An overview of the thiol cofactor systems used by different selenoenzymes and their mimics can be found in this paper, where the authors suggest that molecular recognition and effective binding of the cofactors at the active site of the selenocysteine and their corresponding mimics play crucial roles in the catalytic activity.

TL;DR: The synthesis of the new chiral non-racemic sulfur-containing diselenide, di-2-methoxy-6-[(1S)-1-(methylthio)ethyl]phenyl diselENide, is described, which acts as a strong electrophilic reagent and adds to alkenes to afford the products of selenomethoxylation or selenohydroxylation, respectively, with excellent diastereoselectivities.
