Popis: | Aromatic ketones (R-Ar-CO-R′) have been prepared directly through C–C bond formation using aromatics, aryl, and alkyl acid halides in a Friedel–Crafts reaction over a reusable and catalytically active ordered SnO2–SiO2 three-dimensional mesoporous composite (PS-4) catalyst, which was found to be superior to modified zeolites, functionalized MCM-41, and supported heteropolyacid catalysts. |
