Abstract
Hydrozirconation of arylselenoethynes 1 gave ( E)-2-arylselenovinylzirconium(IV) complexes 2, which reacted with arylsulfenyl chlorides 3 stereoselectively to afford ( E)-1-arylseleno-2-arylsulfanylethenes 4 in good yields. ( E)-1-Arylseleno-2-arylsulfanylethenes 4 could undergo a cross-coupling reaction with Grignard reagents stereoselectively in the presence of a nickel-phosphine complex to give ( E)-vinylic sulfides 5.
