Reaction of a number of aryl styryl ketones with polyphosphoric acid has been investigated and, with the exception of 9-anthryl styryl ketone, each undergoes smooth cyclisation to give an isomeric 5-membered ring ketone. The polyphosphoric acid- and aluminium chloride-catalysed cyclisations of 1-naphthyl styryl ketone, which give 3-phenyl-2,3-dihydrobenz(e)inden-1-one and phenalen-1-one respectively
已经研究了许多芳基苯乙烯基酮与多磷酸的反应,并且除了9烷基苯乙烯基酮以外,每个均进行平滑环化以生成同分异构的5元环酮。讨论了由多磷酸和氯化铝催化的1-萘基苯乙烯基酮的环化反应,它们分别生成3-苯基-2,3-二氢苯并(e)茚满-1-酮和苯仑-1-酮,并作了一般解释根据HSAB理论,提供了1-萘基取代的酮和羧酸的环化模式的描述。
