Abstract
The oligogermane nBu3GeGePh2GenBu3 was photolyzed using UV‐C light in the presence of acetic acid as a trapping agent and the photoproducts were identified using 1H 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 nBu3GeGePh3 was also photolyzed under identical conditions, and in this case the photoproducts were identified as nBu3GeH, nBu3GeOAc, Ph3GeH, Ph3GeOAc and the digermanes nBu6Ge2 and Ph6Ge2.
