Digermenes complexes

The platinum /]2-digermene complex (Ph3P)2Pt(/72-GeMe2GeMe2) was obtained by the elimination of ethylene and IT2 from the oxidative addition of tetramethyldigermane HMe2GeGeMe2H to (Ph3P)2Pt C2H4 (equation 26)111.

Changing the substrate from ethylene to disilene (Scheme 4, M = Si) or digermene (Scheme 4, M = Ge) increases the exothermicity of the reaction (Table 41). For each H2M, M = C, Si, Ge the addition to H2Si=SiH2 is more exothermic than the addition to H2Ge=GeH2 (Table 41)204. In these reactions the complexes and transition states were not studied.
