Synthesis of a manganese germavinylidene complex from bis(germavinylidene).
The reaction of bis(germavinylidene) [(Me3SiN=PPh2)2C=Ge-->Ge=C(PPh2=NSiMe3)2] (1) with CpMn(CO)2(THF) (Cp = eta5-C5H5) in THF afforded [(Me3SiN=PPh2)2C=Ge-->Mn(CO)2Cp] (2). Similar reaction of 1 with (cod)RhCl (cod = 1,5-cyclooctadiene) in THF gave [(Me3SiN=NPPh2)2{(cod)Rh}C-GeCl] (3). The results suggested that reactive germavinylidene may exist in solution. The X-ray structures of 2 and 3 have been determined.
