Organylzinc Chalcogenolate Promoted Michael-Type Addition of α,β-Unsaturated Carbonyl Compounds

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

A recyclable biphasic system for stereoselective and easily handled hydrochalcogenations

Vinyl selenides and vinyl sulfides were prepared by hydrochalcogenation of alkynes with selenols and thiols generated in situ by the reduction of the corresponding diselenides and disulfides with elemental zinc in a biphasic acidic medium. The yields, ste

Organylzinc chalcogenolate promoted michael-type addition of α,β-unsaturated carbonyl compounds

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/NH 4OH system led to organylz

Palladium-catalyzed vinylselenation of allenes

Pd(0)-catalyzed vinylselenation of allenes was found to proceed efficiently in the presence of P(p-MeC6H4)3 as a ligand to afford the corresponding 2-selenomethyl-1,3-dienes. This reaction is highly regioselective and vinyl selenides added to the terminal double bond of the allenes exclusively to introduce the vinyl group at the inner carbon and the selenium moiety at the terminal carbon. The stereochemistry of the double bond of the vinyl selenides was perfectly retained.

Vinylic substitutions promoted by PhSeZnCl: Synthetic and theoretical investigations

Vinyl selenides can be easily obtained through nucleophilic substitution of the corresponding halides by using PhSeZnCl in THF as well as "on water" conditions. The reaction is stereospecific with retention of the alkene geometry. The only exception has b

77Se NMR. 2. The Basis for Application of JSe-Se and JSe-H in Structure Assignments of Mono-, Di-, and Triseleno-Substituted Alkenes

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

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
