Stereoselective Synthesis of (Z)-α-Arylsulfenylvinyl Tellurides Via Hydrozirconation of Alkynyltellurides

Abstract

Hydrozirconation of alkynyltellurides 1 in THF at room temperature gave ( Z)-α- tellurenylvinylzirconium complexes 2, which were reacted with arylsulfenyl chlorides 3 to afford stereoselectively ( Z)-α-arylsulfenylvinyl tellurides 4 in good yields.
