2-Phenylselanyl-1,3-dienes 3-8 were prepared by a Wittig or Wittig-Horner-Emmons procedure starting from α-phenylselanyl α,β-unsaturated aldehydes. Ratio and configuration of each diene isomers were determined by 77Se and 1H NMR. The
Stereoselective synthesis of (Z,E)-2-phenylselenobutadienes by palladium-catalyzed cross-coupling reaction

Hydrozirconation of 1-alkynes gives ( E )-alkenylzirconium complexes 3, which are cross-coupled with (E)-α-phenylselenovinyl bromides (4) in the presence of tetrakis (triphenylphosphine) palladium catalyst to afford (Z,E )-2-phenylselenobutadienes (5) in good yields.
SYNTHESE D'α-HYDROXYALLENES α-FONCTIONNALISES A PARTIR D'α-PHENYLSELENOENALS

Morpholinobenzeneselenenamide (MBSe) react with enals to form α-phenylselenoenals which undergo Wittig and Horner reactions.We synthetise 1-substituted 3-phenylseleno-1,3-butadienes.Oxidation and subsequent 2,3-sigmatropic rearrangement lead to α-fonctionnalized α-hydroxyallenes.This compounds give access to 2,5 dihydrofurans.
