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

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