flammable silanes that are inconvenient to use in chemical reactions. Catalytic amounts of a nickel pincer complex and NaOtBu 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
Me 2 SiH 2,MeSiH 3和SiH 4是气态易燃的硅烷,不方便用于化学反应。据报道,催化量的镍夹杂物和NaO t Bu可以从烯烃和烷氧基氢硅烷合成烷基氢硅烷,从而导致Me 2 SiH 2,MeSiH 3和SiH 4被Me 2(MeO)SiH取代,烯烃的氢化硅烷化反应中的Me(EtO)2 SiH和(MeO)3 SiH。还描述了反应的范围和机理。
