  • Lewis Base Catalyzed Selective Chlorination of Monosilanes
    作者:Alexander G. Sturm、Julia I. Schweizer、Lioba Meyer、Tobias Santowski、Norbert Auner、Max C. Holthausen
    DOI:10.1002/chem.201803921
    日期:2018.12.3
    A preparatively facile, highly selective synthesis of bifunctional monosilanes R2SiHCl, RSiHCl2 and RSiH2Cl is reported. By chlorination of R2SiH2 and RSiH3 with concentrated HCl/ether solutions, the stepwise introduction of Si−Cl bonds is readily controlled by temperature and reaction time for a broad range of substrates. In a combined experimental and computational study, we establish a new mode
    据报道,双官能甲硅烷R 2 SiHCl,RSiHCl 2和RSiH 2 Cl的制备容易,选择性高。通过氯化R 2 SiH 2和RSiH 3在浓盐酸/乙醚溶液中,Si-Cl键的逐步引入很容易受温度和反应时间的控制,适用于多种基材。在一项组合的实验和计算研究中,我们建立了一种新的Si-H键激活模式,该模式由路易斯碱(例如醚,胺,膦和氯离子)辅助。对基本反应机理的阐明表明,通过氢键网络的酒精辅助同样有效且具有选择性。值得注意的是,在中等反应条件下未观察到烷氧基硅烷或硅氧烷的形成。
