Organylzinc Chalcogenolate Promoted Michael-Type Addition of α,β-Unsaturated Carbonyl Compounds
L?ren Nunes, Vanessa,De Oliveira, Ingryd Cristina,Soares Do Rêgo Barros, Olga
supporting information, p. 1525 - 1530 (2015/10/05)
We present the chemo-, regio-, and stereoselective synthesis of vinyl chalcogenide compounds promoted by organylzinc chalcogenolates. In this protocol, reductive cleavage of diorganyl dichalcogenide bonds by the Zn/NH4OH system led to organylzi

77Se NMR. 2. The Basis for Application of JSe-Se and JSe-H in Structure Assignments of Mono-, Di-, and Triseleno-Substituted Alkenes
Johannsen, Ib,Henriksen, Lars,Eggert, Hanne
, p. 1657 - 1663 (2007/10/02)
Series of isomeric mono-, di-, and triseleno-substituted alkenes have been synthesized and subjected to 77Se NMR analysis.In di- and triseleno-substituted alkenes stereochemical assignments were obtained by measurements of 77Se-77Se coupling constants.Val
STEREOCHEMISTRY OF THE NUCLEOPHILIC ADDITION OF SELENOLS TO CARBONYL-CONTAINING ACETYLENE DERIVATIVES
Tsoi, L. A.,Patsaev, A. K.,Ushanov, V. Zh.,Vyaznikovtsev, L. V.
, p. 1897 - 1902 (2007/10/02)
It was shown that the nucleophilic addition of selenols to carbonyl-containing acetylene compounds is highly stereospecific.Acetylenic ketones, propiolic acid, and propiolamide add selenols with the formation of vinyl selenides having only the Z structure
