摘　　要：Alkynylstannanes 1 react with Cp2Zr(H)Cl (Cp=?-C5H5) giving (Z)--stannylvinyl- zirconium complexes 2, which are trapped with NBS or iodine in THF at 0C to stereoselectively afford (Z)-a-bromovinylstannanes and (E)- a-iodovinylstannanes 3, respectively.

关 键 词：HYDROZIRCONATION alkynylstannane (Z)--bromovinylstannane (E)- a-iodovinyl- stannane stereoselective synthesis.
