Article abstract of DOI:10.1007/BF00516199

The reaction of 3,5-di-tert-butyl-o-benzoquinone and 2,6-di-tert-butyl-p-benzoquinone with solutions of 70percent HClO4 in acetic and propionic anhydrides and with boron trifluoride etherate in acetic anhydride leads to the formation of pyrylium salts in high yields.
