can someone please post the bismuth triflate synthesis referenced in that pdf?
this could work like magic for asarone epoxide/glycol acetate?

Bismuth(III) trifluoromethanesulfonate (Bi(OTf)31) can be easily prepared from the reaction of protiodemetallation of triphenylbismuth by a stoichiometric amount of trifluoromethanesulfonic acid. The intermediates Ph3-n Bi(OTf)n[n=2(2),1(3)] have been isolated. This process represents an improvement of the previously reported methods.
