title: A persistent alpha-fluorocarbanion and its analogues: preparation, characterization, and computational study.
abstract: Fluoro power: In agreement with theoretical studies on alpha-fluorocarbanions an X-ray crystal structure shows the alpha-fluorobis(phenylsulfonyl)methide anion adopts a pyramidal configuration (see picture). High-level calculations and NMR spectroscopy studies demonstrate that electron-withdrawing substituents play a crucial role in modulating the properties of bis(phenylsulfonyl)methide anions.
