Synthesis, Structure, and Reactivity of a Thermally Stable Dialkylgermylene

The dialkylgermylene Trp*Ge-2: (Trp*: peripherally extended sterically demanding alkyl groups based on the triptycyl (Trp) framework), was obtained from the reaction of Trp*Li with GeCl2 center dot dioxane. The structure of Trp*Ge-2: was unequivocally determined by NMR and UV-vis spectroscopy, mass spectrometry, and a single-crystal X-ray diffraction analysis. Moreover, the reactivity of Trp*Ge-2: was examined.
