An efficient and simple palladium-catalyzed approach for the synthesis of aryl ketones from low-cost nitriles and arylhydrazines using molecular oxygen (O2) as sole oxidant via C-N bond cleavage is reported. Various aryl ketones were synthesized in moderate to good yields under mild conditions. A possible mechanism involving the PdII/Pd0 catalytic cycle process is depicted, and a cationic palladium intermediate was detected by ESI-MS.
Friedel–Crafts reactions of acyl trifluoromethanesulfonates and cyclic acylsulfonium cations generated from acyl fluorides

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 (or dibenzo[b,e]thiepinones) in 40–85% yield.
Friedel-crafts acylation of arenes with carboxylic acids using polystyrene-supported aluminum triflate

experimental part, p. 155 - 163 (2012/01/02)
Cross-linked polystyrene-supported aluminum triflate (Ps-Al(OTf) 3) has been shown to be a mild, efficient, and chemoselective heterogeneous Lewis acid catalyst for the acylation of aromatic compounds. The catalyst can be easily prepared from cheap starting materials, is stable (as a bench top catalyst) and is reusable.
