Monofluorophosphoranes R3MePF are used in exchange reactions to prepare monofluorinated organic compounds.Tri(n-butyl)methylfluorophosphorane (n-Bu3MePF), easily available, is the most reactive.In solvents of low polarity or even in non-polar solvents, it reacts at -70 deg C with alkyl sulphonates and halides activated by ester, ketone, or ether functions.Thus, fluorinated epoxides can be obtained directly by exchange from their chlorinated or brominated homologues.
