Structurally characterised intermediate of the oxidative addition of a heteroleptic germylene to gallanediyle

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-Mes(2)C(6)H(3), Mes = 2,4,6-Me3C6H2) yielded LGa(mu-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.
