    Publication number: 20130267712
    Abstract: 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.
