Propionyl hexafluoroantimonate

All these cationic deactivation processes were performed with oxolane as the monomer and with various initiators such as triethyloxonium tetrafluoroborate and benzoyl, acetyl or propionyl hexafluoroantimonate. Efficient difunctional cationic initiators such as adipoyl- or terephthaloyl hexafluoroantimonate) can also be used 42 to synthesize bifunctional macromonomers containing at both chain ends a polymerizable double bond. 

Rempp et al. synthesized polytetrahydrofuran macromers by cationic polymerization techniques, using methacryloyl or propionyl hexafluoroantimonate as initiator and then terminating with alcoholates containing the vinyl...
