Synthesis and studies of nucleophilic reactions of vicinal bis(fluorosulfonyloxy)perfluoroisononanes

The addition of peroxydisulfuryl difluoride (FSO3)2 to isomeric perfluoroisononenes (perfluoropropylene trimers) was studied. Isomers containing the trisubstituted C=C bond form 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 perfluoroalkenyl fluorosulfates and products of their subsequent conversions.
