Abstract: A method of preparing aromatic ketones by reaction of aromatic compounds with acyl chlorides or acyl anhydrides in the presence of catalytic amounts of an aromatic polynitrosulfonic acid, and new aromatic ketones derived from an aromatic compound (as the acylatable compound) having at least two nuclear substituents, at least one of said substituents being a nitro group. Both the known and the new aromatic ketones obtainable are valuable intermediates for the production of dyes and pesticides.
