摘要:
A 2-acylamino-2'-carboxy-diphenylmethane is treated with an acid condensing agent such as sulfuric acid or chlorosulfonic acid thereby to produce the corresponding 4-acylamino-anthrone which can then be oxidized, as with hydrogen peroxide or oxygen, to the corresponding 1-acylamino-anthraquinone.
