Formation of a carbon–phosphorus bond between a C–F compound and phosphorus(III) fluorides: a fluorine analogue of the Kinnear–Perren reaction furnishing 1-adamantylfluorophosphoranes

Abstract

Insertion of phosphorus trifluoride into the C–F bond of 1-adamantyl fluoride in the presence of phenyltetrafluorophosphorane leads to formation of the otherwise inaccessible 1-adamantyltetrafluorophosphorane; the formation of a carbon–phosphorus bond is also observed in the systems 1-adamantyl fluoride–Bu^tPF₂–PhPF₄ and 1-adamantyl fluoride-1-adamantyldifluorophosphine-PhPF₄ from which the new compounds 1-adamantyl-t-butyltrifluorophosphorane and bis-(1-adamantyl)trifluorophosphorane, respectively, are obtained.
