Hydrozirconation of internal acetylenic selenides afforded 1,1-bimetalloalkenes, (E)-α-selanylvinylzirconium, which can cross-couple with alkynyliodonium tosylates directly in the presence of Pd(PPh3)4 as the catalyst.
在 Pd(PPh3)4 作为催化剂存在的情况下,内部乙炔硒化氢锆反应生成了 1,1-双金属烷烃 (E)-α-乙炔硒化氢锆,它可以直接与炔基碘鎓对甲苯磺酸盐发生交叉耦合。
