inexpensive reagent. Regioselective nitration of anilides, non-activated and moderately activated aromaticcompounds could be afforded by employing ammonium molybdate and nitric acid as mild and effective nitrating agent. This procedure works efficiently under reflux conditions to prepare mononitroderivatives of anilides, non-activated and moderately activated aromaticcompounds in good to excellent yield with

A method of preparing an aryl carbonyl or aryl thiocarbonyl compound, comprises reacting an N-(nitroaryl)-amide or N-(nitroaryl)-thioamide with an aromatic ring, with a superacid catalyst, to produce the aryl carbonyl or aryl thiocarbonyl compound. The superacid is present in an amount of at most 8 equivalents in proportion to the N-(nitroaryl)-amide or N-(nitroaryl)-thioamide. A method of preparing aryl amide or aryl thioamide, comprises reacting an N-(nitroaryl)-carbamide or N-(nitroaryl)-thiocarbamide with an aromatic ring, with a superacid catalyst, to produce the aryl amide or aryl thioamide.
