Abstract

Abstract The addition of peroxydisulfuryl difluoride (FSO 3) 2 to isomeric perfluoroisononenes (perfluoropropylene trimers) was studied. Isomers containing the trisubstituted C= C bond from adducts which were converted to the corresponding ketofluorosulfates under the action of weak nucleophiles (DMF and AcONa/AcOH) and underwent haloform-type decomposition under the action of CsF to form perfluoroalenyl ...
