Abstract

The reactions of 1-alkynylphosphines with Et₂Zn in the presence of catalytic amounts of Cp₂ZrCl₂ and EtMgBr proceed regio- and stereoselectively to afford (1Z)-alkenylphosphines. The oxidation and sulfonation of synthesized 1-alkenylphosphines with an aqueous solution of hydrogen peroxide or elemental sulfur give (1Z)-alkenylphosphine oxides and (1Z)-alkenylphosphine sulfides, respectively. A plausible scheme for the Zr—Mg-catalyzed 2-zincoethylzincation of 1-alkynylphosphines was proposed.

在 Cp2ZrCl2-EtMgBr 系统催化下取代的 1- 烷炔基膦与 Et2Zn 的反应

在催化剂 Cp2ZrCl2 和 EtMgBr 的存在下，1-烯基膦与 Et2Zn 发生区域和立体选择性反应，生成 (1Z)- 烯基膦。用过氧化氢或元素硫水溶液对合成的 1-烯基膦进行氧化和磺化，可分别得到 (1Z)- 烯基膦氧化物和 (1Z)- 烯基膦硫化物。提出了 Zr-Mg 催化 1-烯基膦的 2-锌乙基锌化反应的合理方案。
