A new method of acetamidation of aromatic compounds based on their reaction with nitroethane in polyphosphoric acid has been developed. Upon the hydrolysis of acetamides during the reaction mixture workup, the corresponding amines can be obtained. Georg Thieme Verlag Stuttgart New York.

Methyl 10-amino-9-anthracenecarboxylate, the preparation of which is described, hardly autoxydizes, and the corresponding 10-imino-9-hydroperoxyde is obtained more easily by photosensitized oxygenation.On the other hand, it is fairly sensitive to electron-abstracting oxydants like PbO2, giving its unsymmetrical dehydrodimer.It cannot be diazotized by the usual nitrosating agents, such as isoamyl nitrite, which lead mostly to 10-methoxycarbonyl-10-nitro-9-anthron.With nitric oxyde in ether, diazotization is also limited owing to an extensive competing reduction to methyl 9-anthroate.Yet, it is shown that a treatment of the amine in ethereal solution by N2O4 gives the corresponding diazonium salts in reasonable yields, the production of nitro-anthron being restricted in these conditions.
