A simple zinc-mediated method for selenium addition to michael acceptors
Evans, Paul,Lenard?o, Eder Jo?o,Monti, Bonifacio,Nacca, Francesca Giulia,Santi, Claudio
, (2020)
In this work, we focused our attention on seleno-Michael type reactions. These were performed using zinc-selenolates generated in situ from diphenyl diselenide 1, 1,2-bis(3-phenylpropyl)diselenide 30, and protected selenocystine 31 via an efficient biphas
Face to face activation of a phenylselenium borane with α,β-unsaturated carbonyl substrates: Facile synthesis of C-Se bonds

Activated olefins directly react with a phenylselenium borane, at room temperature, without any metal or organocatalytic assistance. Up to 10 examples of β-(phenylseleno) substituted ketones and aldehydes have been prepared and theoretical evidence for the mechanism opens up non-existing pathways to create C-heteroatom bonds as a general tool.

"On-water" Michael-type addition reactions promoted by PhSeZnCl

experimental part, p. 1848 - 1851 (2011/05/05)
In this communication we report that our reagent PhSeZnCl can be conveniently used to effect Michael addition like reactions of unsaturated ketones and electron-deficient alkynes, leading to synthetically useful β-seleno derivativesand vinyl selenides, respectively. The reactions are effected at room temperature in THF as well as under "on water" conditions. When the addition occurs on a triple bond, good stereoselectivity is observed, and the reaction shows a rate acceleration in water suspension. Copyright
β-Cyclodextrin-promoted addition of benzeneselenol to conjugated alkenes in water
Srinivas, Boga,Kumar, Vydyula Pavan,Sridhar, Regati,Reddy, Vutukuri Prakash,Nageswar, Yadavalli Venkata Durga,Rao, Kakulapati Rama
experimental part, p. 1080 - 1084 (2009/10/17)
For the first time, a mild and efficient procedure was developed for the conjugate addition of α,β-unsaturated compounds to benzeneselenol providing β-(phenylseleno)-substituted compounds (Scheme). The reaction was promoted by β-cyclodextrin, proceeded in
