, p. 1147 - 1148 (1990)
Both soluble and insoluble polysilanes and an insoluble polygermane have been prepared in high yield and at moderate temperature from the interactions of alkylaryl-, diaryl-, and dialkyl-dichlorosilanes and diphenyldichlorogermane with sodium sand in the

A number of high molecular weight polygermanes were prepared by an improvement on Wurtz coupling reactions of dichlorogermanes and sodium metal, and by a method using diiodogermylene and Grignard reagents (or organolithiums).Most of the polygermanes thus prepared showed a narrow molecular distribution containing molecular weights 103-104.In solution, the polygermanes showed characteristic electronic absorption bands at 300-350 nm and were strongly thermochromic for alkyl-substituted derivatives.Photolysis of the polygermanes proceeded by both contraction of the chain with loss of diorganogermylenes and homolytic scission of the germanium-germanium ? bond.

Photochemistry of aryl-substituted trigermanes. Generation and mechanism of formation of germylenes
Mochida, Kunio,Yoneda, Isao,Wakasa, Masanobu
, p. 53 - 62 (2007/10/02)
Photochemical reactions of aryl-substituted trigermanes have studied by trapping experiments, matrix isolation, and laser flash-photolysis techniques.Photolysis of the phenylated trigermanes involved both the simple extrusion of germylenes and the formati
