Abstract
Abstract The synthesis of stable triacylgermenolates 3 a , b was achieved by using a multiple silyl abstraction methodology. The formation of these new germenolates was confirmed by NMR spectroscopy and UV‐Vis measurements. Moreover, for the triacylgermenolates 2 and 3 a LIFDI mass spectrometry to characterize these new compounds. Germenolates 3 a , b serve as a starting point for a new triaacylgermane 4 a and two octaacyldigermanes 4 c , d . The formation of these acylgermanes was confirmed by NMR spectroscopy, X‐ray crystallography, UV‐Vis measurements and mass spectrometry. The UV‐Vis absorption spectra of 4 c , d show considerably increased band intensities due to the presence of eight chromophores.
