We herein report an effective hydrosilylation of 1,1-disubstituted allenes with a palladium catalyst modified by a monophosphorus ligand, leading to a series of ¦Á-tertiary allylsilanes in high yields and exceptional regiose-lectivities. The employment of BI-DIME is essential for the high reactivities and selectivities. A chiral ¦Á-tertiary allylsilane is formed in excellent ee for the first time by employing a chiral monophosphorus ligand.

钯催化的1,1-二取代的烯丙基硅氢加成反应合成叔丁基硅烷

我们在本文中报道了用单磷配体改性的钯催化剂对1,1-二取代的烯进行有效的硅氢加成反应，从而以高收率和优异的区域选择性产生了一系列α-叔烯丙基硅烷。BI-DIME的使用对于高反应活性和选择性至关重要。通过使用手性单磷配体，首次在优异的ee中形成了手性α-叔烯丙基硅烷。
