Can you post this reference?
I dunno, but I been told ... You never slow down, you never grow old!

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.
