The ozonolysis of anhydroitaconitin which was prepared from itaconitin by the action of acetic or propionic anhydride followed by hydrolysis, yielded, 2, 4-cresotaldehyde liberating acetaldehyde and carbon dioxide. Treatment of the same substance with nitric acid afforded 2, 4, 6-trinitro-m-cresol. These and other experimental results showed that the anhydroitaconitin was an aromatic compound having a m-cresyl grouping with an adjacent ethylenic linkage. The catalytic hydrogenation of anhydroitaconitin in acetone gave dihydroanhydroitaconitin, whereas in alkali gave a carboxylic acid, C14H18O5.
