以keggin 型硅钨酸为催化剂, β-萘酚、醛为原料, 在乙醇和无溶剂两种体系中, 分别合成了1,1'-烷基(芳基)二-2-萘酚和14-烷基(芳基)-14H-二苯并[a,j]氧杂蒽两类化合物. 该方法不仅反应时间短, 产率高, 后处理简单易分离, 而且催化剂价廉易得, 对环境友好.

关键词: 氧杂蒽, 醛, β-萘酚, 硅钨酸

Under ethanol and solvent-free conditions, 1,1'-alkyl(aryl)-bis(naphthalen-2-ol) and 14-alkyl(aryl)-14H-dibeno[a,j]xanthenes were successfully synthesized from β-naphthol and aldehydes by using silicotungstic acid with keggin structure as the catalyst. The reaction catalyzed by silicotungstic acid has the advantage of short reaction time, high yield, simple workup procedures and easy isolation. The catalyst was inexpensive and environmentally friendly.

Key words: xanthene, aldehyde, β-naphthol, silicotungstic acid
