Compounds carrying reactive fluorine atoms, such as methylphosphonic difluoride and perfluoroisobutene, undergo facile exchange with organosilanes and stannanes. Reactions with protic nucleophiles also yield similar products. To account for the products formed and observed reactivity differences, appropriate mechanisms are proposed. The reactions described herein have considerable synthetic utility
It has been found that perfluoropropylene, perfluoroisobutylene and analogous substances react with SbF5 to form stable allylic cations, which have been observed by NMR 13C, 19F spectra.
