N-Triflyloxy amides undergo ionization in refluxing isopropanol to give N-acyliminium ions which can be trapped by addition of allyltrimethylsilane to the reaction mixture. Alternatively they can be converted to N-(isopropoxy)alkyl amides and then back to N-acyliminium ions under a variety of conditions.
