The oligogermane nBu3GeGePh2GenBu3was photolyzed using UV-C light in the presence of acetic acid as a trapping agent and the photoproducts were identified using1H NMR spectroscopy, gas chromatography/electron-impact mass spectrometry, and high resolution accurate mass mass spectrometry. The products identified were the germanes nBu3GeH, nBu3GeOAc, and Ph2Ge(H)OAc (OAc = C2H3O2) and the digermane nBu6Ge2. This indicates that both germanium–germanium single bonds are cleaved homolytically upon irradiation to generate two nBu3Ge·radicals and the germylene Ph2Ge:. The digermane nBu3GeGePh3was also photolyzed under identical conditions, and in this case the photoproducts were identified as nBu3GeH, nBu3GeOAc, Ph3GeH, Ph3GeOAc and the digermanes nBu6Ge2and Ph6Ge2.
Cp2TiCl2 catalyzed one-pot synthesis of n-Bu3GeH from GeCl4

The reaction of GeCl4 with n-BuMgCl in presence of a catalytic amount of Cp2TiCl2 gives n-Bu3GeH and n-Bu4Ge in ca. 70 and 25% yield, respectively. This method provides an industrially feasible one-pot synthesis for Bu3GeH and Bu4Ge. The reaction temperature and stoichiometry seem to be important in the distribution of the products. Apart from elemental analysis these compounds have been characterized by comparing their boiling points, NMR spectral data and GC assay with that of the authentic samples.
