Cp*2NdCH(SiMe3)2 efficiently catalyzes hydrosilation of 1,3-, 1,5-, and 1,6-dienes under mild conditions with unusual selectivities as compared with later transition metal-catalyzed reactions; hydrosilation of isoprene affords mainly (E)-, not (Z)-, allylsilane. On the other hand, hydrosilation of 1,5- and 1,6-dienes proceeds through intramolecular CC bond formation to give (silylmethyl)-cyclopentanes
与后来的过渡金属催化反应相比,Cp * 2 NdCH(SiMe 3)2在温和条件下以不同寻常的选择性有效催化1,3-,1,5-和1,6-二烯的硅氢化反应。异戊二烯的氢硅化主要提供(E)-,而不是(Z)-烯丙基硅烷。另一方面,通过分子内CC键的形成进行1,5-和1,6-二烯的硅氢化反应,得到(甲硅烷基甲基)-环戊烷。
