Vinyl alkyl selenides can be dealkylated by nucleophilicsubstitution or by electron transfer to give vinyl selenide anions which retain the configuration of the starting products. The same anions are also produced by electron transfer from vinyl acetyl selenides. The vinyl selenide anions react with vinylhalides, in DMF or DMA, to give divinyl selenides. These reactions occur with retention of configuration

The insertion of elemental selenium into the Csp2-Zr bond of alkenylchlorozirconocenes affords (E)-vinylseleno zirconocenes, which were trapped by acyl chlorides giving (E)-vinylic selenol esters in good yields.
