Synthesis of novel metal-germavinylidene complexes from bisgermavinylidene

The bisgermavinylidene [(Me3SiN=PPh2) 2C=Ge→Ge=C(PPh2=NSiMe3)2] (1) has been used as the source of unstable germavinylidene for the synthesis of a series of metal-germavinylidene complexes. Treatment of 1 with M(PPh 3)4 (M = Ni, Pd) afforded the metal-germavinylidene complexes [{(Me3SiN=PPh2)2C=Ge} 2Ni(PPh3)2] (2) and [{(Me3SiN= PPh2)2C= Ge-μ2}Pd(PPh3)] 2 (3), respectively. The germavinylidene moiety from 1 acts as a two-electron terminal and bridging ligand, respectively. Similar reaction of 1 with AgCl or Aul gave [(Me3-SiN=PPh2)2C=Ge(Ag) (Cl)]2 (5) and [(Me3SiN=PPh2) 2C=Ge(Au)(I)]2 (6), respectively. The result has shown that the germavinylidene moiety from 1 behaves as a Lewis base and undergoes an insertion reaction into the metal-halogen bond. X-ray structures of 2, 3, 5, and 6 have been determined.
