Pyrolysis of pentamethyldigermane leads to the formation of dimethylgermylene as a short-lived intermediate that inserts into a germanium–hydrogen bond of its precursor.

reactions of vinyl-, styryl-, and benzyl-substituted digermanes were investigated by chemical trapping experiments. Photolysis of vinylpentamethyldigermane afforded 1-trimethyl-2-(pentamethyldigermyl)ethane as a major product, and styrylpentamethyldigermanes gave mainly styryltrimethylgermane. On the other hand, photolysis of benzyl-substituted digermanes (benzylpentamethyldigermane and 1,2-dibenzyltetramethyldigermane)
Preparation, Structural Characterization, and Reactivities of (Digermanyl)lithium. Its Application to the Synthesis of Bis(1,1-diphenyl-2,2,2-trimethyldigermanyl)platinum(II)
(Pentamethyldigermanyl )lithium (Me 3 GeGeMe 2 Li, la) and (1,1 -diphenyl-2,2,2-trimethyldigermanyl)lithium (Me 3 GeGe-Ph 2 Li, 1b) were prepared and characterized by spectroscopic methods. The structure of (digermanyl)lithium 1b was established by X-ray diffraction. The reaction of 1b with cis-PtCl 2 -(PMe 2 Ph) 2 gave the expected substitution product, transPt(Me 3 GePh 2 Ge)2(PMe2Ph)2.
