Bond activation reactions using main group metal complexes are gaining increasing interest. We report on reactions of LGa (L = HC[C(Me)N(Ar)], Ar = Dipp = 2,6--PrCH,) with heteroleptic tetrylenes L'ECl (E = Ge, Sn; L' = N(SiMe)Ar), yielding the donor-acceptor complex LGa-Sn(Cl)L' (1) or the oxidative addition product L(Cl)GaGeL' (3). The reaction with DMPGeCl (DMP = 2,6-MesCH, Mes = 2,4,6-MeCH) yielded LGa(μ-Cl)GeDMP (2), which represents an intermediate of the oxidative addition reaction. 1-3 were characterized by NMR and IR spectroscopy as well as by single crystal X-ray diffraction (sc-XRD), while their electronic nature was analyzed by quantum chemical calculations.
使用主族金属配合物的键活化反应正越来越受到关注。我们报道了LGa(L = HC[C(Me)N(Ar)],Ar = Dipp = 2,6 - -PrCH₂)与杂配四价元素化合物L'ECl(E = Ge,Sn;L' = N(SiMe₃)Ar)的反应,生成供体-受体配合物LGa - Sn(Cl)L'(1)或氧化加成产物L(Cl)GaGeL'(3)。与DMPGeCl(DMP = 2,6 - MesCH₂,Mes = 2,4,6 - Me₃CH)的反应生成了LGa(μ-Cl)GeDMP(2),它是氧化加成反应的中间体。通过核磁共振(NMR)、红外光谱(IR)以及单晶X射线衍射(sc-XRD)对1 - 3进行了表征,同时通过量子化学计算分析了它们的电子性质。
