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.
most promising compounds, the thiourea compound 6g exhibited significant cytotoxic activity against human melanoma A2058 cells that was twice as high as that of capsaicin. Compound 6g induced significant and dose-dependent G0/G1 cell cycle arrest in A2058 cells triggering cell death by apoptosis. Our results suggest that 6g modulates the RAF/MEK/ERK pathway, inducing important morphological changes
