We disclosed a state-of-the-art strategy for the asymmetric synthesis of enantioenriched silicon-stereogenic benzosiloles in excellent yields and enantioselectivities enabled by a Ni0/chiral PR3-catalyst system. Moreover, preliminary studies on the chiroptical properties of silicon-stereogenic bis-silicon-bridged π-extended systems, which were synthesized by the presented catalysis strategy, are also
我们公开了一种以优异的产率和对映选择性不对称合成对映体富集的硅立体苯并硅烷的最先进的策略,该方法由 Ni 0 /手性 PR 3催化剂系统实现。此外,还描述了对通过所提出的催化策略合成的硅立体双硅桥连 π 扩展系统的手性光学特性的初步研究。

Synthesis of 2-methylidene-1-silacyclohexanes from 2,6-dibromohex-1-ene and polyhalosilanes
作者:Silvia Díez-González、Luis Blanco
DOI:10.1016/j.jorganchem.2006.08.061
日期:2006.12
Various 2-methylidene-l-silacyclohexanes were prepared by straightforward syntheses from readily available polychloro- or polyfluorosilanes, magnesium and 2,6-dibromohex-l-ene using Barbier-type conditions or a previously synthesized Grignard reagent. Good yields were obtained considering the low stability of the products in the reaction conditions. (c) 2006 Elsevier B.V. All rights reserved.
