Me2SiH2, MeSiH3, and SiH4 are gaseous and flammable silanes that are inconvenient to use in chemical reactions. Catalytic amounts of a nickel pincer complex and NaO(t)Bu are reported to allow the synthesis of alkyl hydrosilanes from alkenes and alkoxy hydrosilanes, leading to the replacement of Me2SiH2, MeSiH3, and SiH4 by Me2(MeO)SiH, Me(EtO)2SiH, and (MeO)3SiH in hydrosilylation reactions of alkenes. The scope and mechanism of the reactions are also described.
Me2SiH2、MeSiH3 和 SiH4 是气态易燃的硅烷,在化学反应中使用不方便。据报道,催化量的镍钳形配合物和 NaO(t)Bu 允许烯烃和烷氧基硅烷合成烷基氢硅烷,从而在烯烃的氢硅烷化反应中用 Me2(MeO)SiH、Me(EtO)2SiH 和(MeO)3SiH 取代 Me2SiH2、MeSiH3 和 SiH4。还描述了反应的范围和机理。
