They also produced the benzyl 20 Mikhail G. Voronkov and Klavdiya A. Abzaeva derivatives of 2,2-dimethyl-1,3-dioxa-2-germacyclopentane and 2,2-dimethyl-1,4-dioxa-2germacyclohexane392 . The second approach280 to compounds R3 GeOR0 was the addition reaction of R2 GeH to carbonyl compounds in the presence of copper powder. In 1964, Satge362 used a re-alkoxylation reaction, with alcohols having boiling points higher than those of MeOH or EtOH, to replace the alkoxy group in R3 GeOR0 (R0 D Me, Et) by another alkoxy group.

The Ph3 GeONa was prepared by oxidation of Ph3 GeNa in the same solvent. In 1966, the synthesis of Ph3 GeOH by a slow hydrolysis of Ph3 GeH380 was reported. Dennis and Patnode167 assumed the existence of trimethylgermanol, but neither they nor Schmidt and Ruidisch371 succeeded in isolating it. Schmidt and Ruidisch used titrimetric and cryoscopic methods to show that Me3 GeCl was hydrolyzed by water to Me3 GeOH, 18 Mikhail G. Voronkov and Klavdiya A. Abzaeva but its attempted isolation from the aqueous solution failed and only Me3 GeOGeMe3 was isolated.

In 1961–1964 Schmidbaur, Schmidt and coworkers405,416 , synthesized a series of compounds R4 n Ge(OSiR03 )n with R, R0 D Me, Et; n D 1–3. For example, trimethyl(trimethylsiloxy)germane Me3 GeOSiMe3 and dimethylbis(trimethylsiloxy)germane Me2 Ge(OSiMe3 )2 were obtained by the reaction of alkali metal trimethylsilanolates Me3 SiOM and Me3 GeCl or Me2 GeCl2 . Schmidbaur and Schmidt409 studied the cleavage of trimethyl(trimethylsiloxy)germane with sulfuric and chromic anhydrides (SO3 and CrO3 ), which gave Me3 GeOSO2 OSiMe3 and Me3 GeOCrO2 OSiMe3 , respectively.
