1.0]hexen-2-one VIII, a dienone IX, and a phenol X together with 2,4,6-tri-t-butylphenol. The bicyclohexenone VIII was shown to be an intermediate in the formation of the dienone IX. On the other hand, irradiation of 2,6-di-t-butyl-4-methyl-6-acetoxy-2,4-cyclohexadienone (VIb) afforded a dienone XI, two phenols XII and XIII, and a ketone XIV. The phenol XII and the dienone XI were not obtained by the
2,4,6-三叔丁基-6-乙酰氧基-2,4-环己二酮(VIa)在苯中的光解产生了双环[3.1.0]己烯-2-酮VIII,二烯酮IX和苯酚X与2,4,6-三叔丁基苯酚一起。显示双环己烯酮VIII是二烯酮IX形成的中间体。另一方面,照射2,6-二叔丁基-4-甲基-6-乙酰氧基-2,4-环己二酮(VIb)得到二烯酮XI,两种酚XII和XIII以及酮XIV。苯酚XII和二烯酮XI不是通过酮XIV的光解而获得的,而酮XIV可能是通过VIb的骨架重排而形成的。结果表明,VI型2,4,6-三烷基-6-乙酰氧基-2,4-环己二烯酮的光芳香化可能通过VIII型中间体进行,该中间体可能由二烯酮VI通过乙酰氧基迁移与键交替形成而形成。 。
