ChemInform Abstract: Reaction of the Fluoride Anion with Acetonitrile, Chloroform, and Methylene Chloride.

ChemInform Abstract

¹⁹F and ¹H NMR spectra of solutions of anhydrous HF₂^--free tetramethylammonium fluoride (I) in acetonitrile, chloroform, or dichloromethane reveal that the fluoride anion is basic enough to abstract a proton from acetonitrile and nucleophilic enough to undergo halogen exchange reactions with chloroform and dichloromethane at room temperature.
