Synthesis, LIFDI Mass Spectrometry and Reactivity of Triacyl‐Germenolates

The synthesis of stable triacylgermenolates 3 a,b was achieved by using a multiple silyl ion 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 n...

Description
Summary:The synthesis of stable triacylgermenolates 3 a,b was achieved by using a multiple silyl ion 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. New Germenolates. A multiple silyl ion pathway was used to isolate two new germenolates. Their formation was confirmed by NMR spectroscopy, UV−Vis measurements as well as LIFDI mass spectrometry was used to exclude any radical side products. These germenolates serve as a starting point for new acylgermanes.
