    esters to terminal alkynes can be switched by the choice of phosphorus ligands on the palladium catalysts. The silaboration proceeds with normal regioselectivity in the presence of (eta(3)-C(3)H(5))Pd(PPh(3))Cl (1.0 mol %) to give 1-boryl-2-silyl-1-alkenes in high yields. In sharp contrast, selective formation of the inverse regioisomers, 2-boryl-1-silyl-1-alkenes, takes place when the reaction is carried
    将甲硅烷基硼酸酯加成到末端炔烃的区域选择性可以通过选择钯催化剂上的磷配体来改变。在 (eta(3)-C(3)H(5))Pd(PPh(3))Cl (1.0 mol %) 存在下,硅化反应以正常的区域选择性进行,得到 1-boryl-2-silyl-1-烯烃收率高。与此形成鲜明对比的是,当使用带有 P(t-Bu)(2)(biphenyl-2-) 的钯催化剂进行反应时,会选择性地形成逆区域异构体,即 2-boryl-1-silyl-1-烯烃。 y)。提出了涉及可逆插入/β-硼酸消除步骤的区域选择性变化的反应机制。

    Palladium(0)-catalyzed carbocyclization of 1,7-enynes mediated by (chlorodimethylsilyl)pinacolborane proceeds with 1,8-addition of the silicon and boron functions to give functionalized cyclohexane derivatives with boron attached to the exocyclic olefin.
