Small-molecule activation by low-valent main-group element compounds is of general interest. We here report the synthesis and characterization ( H, C, Si NMR, IR, sc-XRD) of heteroleptic metallasilylenes L (Cl)MSiL (M=Al 1, Ga 2, L =HC[C(Me)NDipp] , Dipp=2,6- Pr C H ; L =PhC(N Bu) ). Their electronic nature was analyzed by quantum chemical computations, while their promising potential in small-molecule activation was demonstrated in reactions with P , which occurred with unprecedented [2+1+1] fragmentation of the P tetrahedron and formation of L (Cl)MPSi(L )PPSi(L )PM(Cl)L (M=Al 3, Ga 4).
低价主族元素化合物对小分子的活化作用受到广泛关注。我们在此报告了杂配金属硅烯L（Cl）MSiL（M = Al 1，Ga 2，L = HC[C（Me）NDipp]，Dipp = 2,6 - Pr C H ；L = PhC（N Bu） ）的合成与表征（H、C、Si NMR、IR、单晶X射线衍射）。通过量子化学计算分析了它们的电子性质，同时在与P的反应中展示了它们在小分子活化方面的潜在应用前景，该反应发生了前所未有的P四面体[2 + 1 + 1]碎片化，并形成了L（Cl）MPSi（L ）PPSi（L ）PM（Cl）L（M = Al 3，Ga 4）。
