Reactive acyl trifluoromethanesulfonates are formed from the reaction of acyl fluorides with trimethylsilyl trifluoromethanesulfonate (TMSOTf). These electrophiles undergo Friedel–Crafts reactions with electron-rich aromatics at room temperature. When a sulfur atom is present at their γ position, their cyclization to acylsulfonium cations is observed and is followed by a rearrangement leading to benzothiepinones
