A catalytic synthesis of deuterated silanes SiEt3D, SiMe2PhD and SiPh2D2 is reported that allows their facile generation in a 3–4 g scale, utilizing D2 (0.5 bar) as the hydrogen isotope source and low catalyst loadings (0.01 mol%). The catalyst precursor is the rhodium (III) complex 1, which contains a (η5-C5Me5)Rh cation stabilized by coordination to a cyclometallated phoshine PMeXyl2 (Xyl = 2,6-C6H3Me2)
据报道,氘代硅烷 SiEt3D、SiMe2PhD 和 SiPh2D2 的催化合成允许它们以 3-4 g 的规模轻松生成,利用 D2 (0.5 bar) 作为氢同位素源和低催化剂负载 (0.01 mol%)。催化剂前体是铑 (III) 络合物 1,它包含 (η5-C5Me5)Rh 阳离子,通过与环金属化膦 PMeXyl2 (Xyl = 2,6-C6H3Me2) 配位而稳定。同样的配合物也是各种酮、醛和 α,β-不饱和腈的 CO 和 C≡N 键的氢化硅烷化的活性催化剂。因此,这两种特性的组合允许开发用于这些底物的氘代硅烷化的简单且熟练的单烧瓶、两步程序。版权所有 © 2011 John Wiley & Sons, Ltd.
