The tris(pentafluoroethyl)silanide anion is accessible by the deprotonation of Si(C F ) H at low temperatures. Subsequent quenching of the resulting salt-like compounds with suitable electrophiles, such as transition-metal complexes or Group 14 element halides, leads to a plethora of novel tris(pentafluoroethyl)silane derivatives. This underlines the versatility of Li[Si(C F ) ] as a powerful nucleophilic transfer reagent.
三（五氟乙基）硅烷阴离子可通过低温下 Si(CF3)5H 的去质子化得到。随后，用合适的亲电试剂（如过渡金属配合物或第 14 族元素卤化物）猝灭所得类似盐的化合物，可得到大量新型三（五氟乙基）硅烷衍生物。这突出了 Li[Si(CF3)5]作为一种强大的亲核转移试剂的多功能性。
