TL;DR: In this paper, the reactions of l'iodure de methyl-Mg and celles du bromure de phenylmg avec le benzo [b] thiophene, le thianthrene, le dibenzothiophene and le dihydro-2,3 thiopyranne in presence of [trimethylene bis-diphenylphosphino] 2 NiCl 2
Abstract: On etudie les reactions de l'iodure de methyl-Mg et celles du bromure de phenyl-Mg avec le benzo [b] thiophene, le thianthrene, le dibenzothiophene et le dihydro-2,3 thiopyranne en presence de [trimethylene bis-diphenylphosphino] 2 NiCl 2

TL;DR: In the case of MeSeLi, the only reaction occurring is the aliphatic substitution which affords the vinyl thiolate anions, as an equilibrium mixture of the (E)- and (Z)- isomers, or the vinyl selenide anions which retain the configuration of the starting styryl alkyl selenides as discussed by the authors.

TL;DR: In this paper, the configuration of the vinyl methyl selenides from which they are produced by demethylation has been investigated and a three-stage one-pot stereospecific synthesis of vinyl alkyl selenide from unactivated vinyl halides has been proposed.
