在这篇文章中，我们介绍了硅、锗和锡的五氟乙基化化合物。五氟乙基明显的吸电子效应导致中心原子的刘易斯酸度显著增加，从而导致高价配合物、阴离子元素（II）种的稳定以及元素-元素和元素-氢键的显著反应活性。通过加入不饱和的C-C键或与有机卤化物以及过渡金属配合物反应，可以很容易地得到带有五氟乙基元素基的分子。此外，利用五氟乙基有助于形成供体稳定的二甲苯和乙烯。一系列这样的化合物可用作合适的五氟乙基化试剂。与经过充分研究的三氟甲基衍生物相反，这些化合物通常表现出更高的热稳定性，从而可以更方便地处理。
In this contribution we present an account on pentafluoroethylated compounds of silicon, germanium and tin. The pronounced electron-withdrawing effect of the pentafluoroethyl group leads to a markedly increased Lewis acidity at the central atom which results in the stabilization of hypervalent complexes, anionic element(II) species as well as remarkable reactivities of element-element and element-hydrogen bonds. By addition to unsaturated C-C bonds or by reaction with organic halides as well as transition-metal complexes the molecules bearing a pentafluoroethyl-element group are readily accessible. Moreover, the utilization of pentafluoroethyl groups facilitates the formation of donor-stabilized germylenes and stannylenes. A series of such compounds serves as suitable pentafluoroethylation reagents. Conversely to the well-studied trifluoromethyl derivatives these compounds frequently exhibit a higher thermostability, which allows a more convenient handling.
