摘要
-Fluorocarbanions are key intermediates in nucleophilic fluoroalkylation reactions. Although frequently discussed, the origin of the fluorine effect on the reactivity of -fluorinated CH acids has remained largely unexplored. We have now investigated the kinetics of a series of reactions of -substituted carbanions with reference electrophiles to elucidate the effects of -F, -Cl, and -OMe substituents on the nucleophilic reactivities of carbanions.
