Activation of non-polar bonds by an electron-rich gallagermylene

Abstract

The electron-rich germylene LGa(μ–Cl)GeAr^Mes (1) (L = CH[C(Me)N(Dipp)]₂, Dipp = 2,6-ⁱPr₂C₆H₃, Ar^Mes = 2,6-Mes₂C₆H₃, Mes = 2,4,6-Me₃C₆H₂) shows promising potential in the σ-bond activation of unpolar molecules as is shown in oxidative addition reactions with H₂ and P₄, yielding L(Cl)GaGe(H)₂Ar^Mes (2) and L(Cl)Ga(P₄)GeAr^Mes (3). Compounds 2 and 3 were characterised spectroscopically (¹H, ¹³C{¹H}, (³¹P{¹H}), IR) and by single-crystal X-ray diffraction (sc-XRD).
