Abstract

Abstract : Reactions of gallanediyl LGa with heteroleptic tetrylenes L′ECl gave the donor–acceptor complex LGa–Sn(Cl)L′ (1 ), the oxidative addition product L(Cl)GaGeL′ (3 ) and LGa(μ–Cl)GeL′ (2 ), an isolable intermediate of the oxidative addition reaction. Abstract : 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 -Pr2 C6 H3, ) 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-Mes2 C6 H3, Mes = 2, 4, 6-Me3 C6 H2 ) 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.
