Introduction
Fluorinated alkyl substituents appear widely in medicinal and pharmaceutical chemistry [1,2,3,4,5,6,7], and [18F]-fluorinated ethyl or propyl tags are increasingly common tools radiochemists use to prepare [18F]-labeled radiopharmaceuticals for positron emission tomography (PET) [8,9,10,11]. Numerous fluorinating reagents that are available to prepare alkyl fluorides through nucleophilic, electrophilic, and radical approaches are covered elsewhere in this volume. Here we will review fluorinations with the readily available and prototypical nucleophilic fluorinating reagent tetrabutylammonium fluoride (TBAF) and its derivatives.
In the gas phase, fluoride is an incredibly potent nucleophile and strong base because of its concentration of charge (as the smallest monoanion) and because of its propensity to form very strong bonds with hydrogen and carbon. In solution, the situation is quite different: strong ion pairing with cations, dipolar interactions with solvent...
