Bond activation reactions using main group metal complexes are gaining increasing interest. We report on reactions of LGa (L = HC[C(Me)N(Ar)]₂, Ar = Dipp = 2,6-i-Pr₂C₆H₃,) with heteroleptic tetrylenes L′ECl (E = Ge, Sn; L′ = N(SiMe₃)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-Mes₂C₆H₃, Mes = 2,4,6-Me₃C₆H₂) 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.

杂配子锗烯与没食子二烯的氧化加成的结构特征中间体

使用主族金属配合物的键活化反应越来越受到关注。我们报告了 LGa (L = HC[C(Me)N(Ar)] ₂ , Ar = Dipp = 2,6- i -Pr ₂ C ₆ H ₃ ,) 与杂配四萘嵌苯 L'ECl (E = Ge , Sn; L' = N(SiMe ₃ )Ar)，得到供体-受体复合物 LGa-Sn(Cl)L' ( 1 ) 或氧化加成产物 L(Cl)GaGeL' ( 3 )。与 DMPGeCl (DMP = 2,6-Mes ₂ C ₆ H ₃ , Mes = 2,4,6-Me ₃ C ₆ H ₂ ) 反应生成 LGa(μ–Cl)GeDMP ( 2)，它代表氧化加成反应的中间体。通过核磁共振和红外光谱以及单晶 X 射线衍射 (sc-XRD) 对1-3进行了表征，而通过量子化学计算分析了它们的电子性质。
