The synthesis of 6-bromo-2,2-di-tert-butyl-4H-1,3,2-benzo[d]dioxagermine (1) via an alcohol/alkoxide exchange starting from di-tert-butyl-di-ethoxy germane is reported. Characterization of the title compound including single crystal X-ray diffraction and TGA/DSC analysis, mass spectrometry, H-1 NMR, C-13H-1} NMR and IR spectroscopy is reported. DFT-D calculations have been carried out to assign the absorption band maxima of the IR spectrum to the corresponding vibrational modes. The suitability for Twin Polymerization of the novel dioxagermine 1 has been studied by TGA/DSC analysis and mass spectrometry. Proton-assisted Twin Polymerization of 1 results in an organic-inorganic hybrid material composed of a phenolic resin and [(Bu2GeO)-Bu-t](n). (C) 2013 Elsevier B.V. All rights reserved.
