Abstract

The tris(pentafluoroethyl)silanide anion is accessible by the deprotonation of Si(C2 F5 )3 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(C2 F5 )3 ] as a powerful nucleophilic transfer reagent.
