描述了一种极其庞大且高效的空间保护基团 2,4,6-三[双(三甲基硅基)甲基]苯基（在本文中表示为 Tbt）在锗和较重硫族原子之间的一系列双键化合物（我们为这一较重的锗酮同系物家族创造了“含锗重酮”这一术语）之间的一系列双键化合物的动力学稳定中的应用。 Tbt 基团与其他一些大的芳香族或烷基取代基的组合使我们能够合成新型含锗双键物质 [Tbt(R)Ge=X; R = 2,4,6-三异丙基苯基（Tip）或双（三甲基硅基）甲基（Dis）]，例如锗硫酮（X = S）、锗烷酮（X = Se）和锗烷四酮（X = Te）是稳定的结晶化合物，而锗酮[Tbt(Tip)Ge=O]是含锗重酮中反应性最强的物质，被发现很难分离，因此仅由捕获反应证明。德国分离物的 X 射线晶体分析...
The recent applications of an extremely bulky and efficient steric protection group, 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (denoted as Tbt in this article), to the kinetic stabilization of a series of doubly bonded compounds between germanium and heavier chalcogen atoms (we coin the expression “germanium-containing heavy ketones” for this family of heavier congeners of germanone) are described. Combination of a Tbt group with some other bulky aromatic or alkyl substituent enabled us to synthesize the novel germanium-containing double-bond species [Tbt(R)Ge=X; R = 2,4,6-triisopropylphenyl (Tip) or bis(trimethylsilyl)methyl (Dis)] such as germanethiones (X = S), germaneselones (X = Se), and germanetellones (X = Te) as stable crystalline compounds, while the germanone [Tbt(Tip)Ge=O], the most reactive species among the germanium-containing heavy ketones, was found to be very difficult to isolate and was evidenced only by the trapping reactions. The X-ray crystallographic analysis of the isolated german...
