Reactions of nucleophilic reagents with dianionic hexacoordinated germanium complexes: A new convenient route to functional organogermanes from germanium dioxide
Cerveau,Chuit,Corriu,Reye
, p. 786 - 787 (1988)
Tetraorganogermanes and triorganogermanes can be prepared in two steps from GeO2: the preparation of the anionic hexacoordinated germanium complexes followed by reaction of these with Grignard reagents to give the organogermanes.

Preliminary communication. Kinetic spectroscopy of diphenylgermylene Ph2Ge following laser flash photolysis of bis(trimethylsilyl)diphenylgermane (Me3Si)2GePh2
Konieczny, Stanislaw,Jacobs, S. Joshua,Wilking, Janet K. Braddock,Gaspar, Peter Paul
, p. C17 - C22 (1988)
A transient, λmax 445 nm, was observed in the 266 nm laser flash photolysis of cyclohexane solutions of (Me3Si)2GePh2, and rate constants were recorded for its disappearance in the presence of various trapping agents.The reactivity profile is in accord with the identification of the carrier as diphenylgermylene Ph2Ge, that dimerizes to tetraphenyldigermene Ph2Ge=GePh2, λ7max3 320 nm.

Novel germanium containing triflates were prepared from the reactions of trifluoromethanesulfonic acid with tetraphenylgermane (1) and digermanes (Ph3GeGeMe3 (4), Ph3GeGePh3 (5)). The improved procedures for synthesis of known organogermanium compounds (Ph4Ge (1), Ph3GeCl (2), Ph3GeGeMe3 (4), Ph3GeGePh3 (5)) were also presented. The crystal structure of Ph3GeOTf (6) and Ph2Ge(OTf)Ge(OTf)Ph 2 (7) was studied by X-ray analysis. In 7 each germanium atom is pentacoordinated due to intramolecular interaction with O atom of the neighboring triflate group.
Reactions of organochlorosilanes with chloro-and organogermanes in the presence of aluminum chloride
Zhun,Sbitneva,Polivanov,Chernyshev
, p. 1564 - 1570 (2008/02/09)
The effect of substituents at the silicon and germanium atoms in reactions of organochlorosilanes with chloro-and organogermanes in the presence of aluminum chloride was studied. The only occurring process is the exchange of the chlorine atoms at Ge for the phenyl groups from Si; an increase in the number of methyl groups or chlorine atoms at Si promotes formation of phenyltrichlorogermane, and an increase in the number of phenyl groups or replacement of the chlorine atom at the Si atom by hydrogen leads to the formation of di-and triphenylchlorogermanes. Neither phenyl nor other radicals are transferred back from Ge to Si in the course of reactions of phenylgermanes with methylchlorosilanes in the presence of aluminum chloride; the only occurring processes are the exchange of the phenyl or methyl radicals bonded to Ge for the Cl atom bonded to Al and the disproportionation of phenylchlorogermanes.
