Treatment of 5,5-dimethyl-2-cyclohexen-1-one and isophorone with phosphomolybdic acid, potassium dichromate, cupric sulfate, and air gives 5,5-dimethyl- and 3,5,5-trimethyl-2-cyclohexene-1,4-dione, respectively. In the latter reaction treatment of the crude product with aqueous base leads to the formation of 2,3,6,7-tetrahydro-2,2,6,6,-tetramethylanthracene-1,4,5,8-tetrone.
用磷钼酸、重铬酸钾、硫酸铜和空气处理 5,5-二甲基-2-环己烯-1-one 和异佛尔酮,得到 5,5-二甲基-和 3,5,5-三甲基-2-环己烯-1 ,4-二酮,分别。在后一反应中,粗产物用碱水溶液处理导致形成 2,3,6,7-四氢-2,2,6,6,-四甲基蒽-1,4,5,8-丁酮。
