Reactivity of a 1-germapropadiene

α-Lithiofluorogermane 3 eliminated lithium fluoride to give 1-germapropadiene 1 even at -75°C. The reactivity of 1-germapropadiene 1 was investigated. Compound 1 was not stable above 0°C in solution or 90°C in the solid state. Two C-H insertion cyclic compounds, 8 and 9, were formed as a result of decomposition. Water, methanol, and ethanol added across the Ge=C double bond of 1 to give vinylalkoxy (hydroxy) germanes. Benzophenone did not react with 1 at 0°C, but benzaldehyde gave oxagermetane 13 in good yield. When acetone was introduced to 1, it gave the unexpected product 10, the water adduct.

Synthesis and structure of a 1-germapropadiene

The reaction of t-BuLi with a fluoroalkynyl-germane produces the title compound, 1. Single-crystal X-ray analysis shows the Ge=C bond length to be 1.783(2) ?. The Ge atom is somewhat pyramidalized, and the Ge=C=C bond angle (159.2°) reveals a bent structure at the central carbon atom.
