摘　　要：以芳醛、丙二腈、2-(1,2-二氢-3-亚茚基)丙二腈或2-(2,3-二氢-4H-亚萘基)丙二腈为原料,乙醇为溶剂,在80℃下以KF/Al2O3为催化剂合成了一系列芴或菲的衍生物,该方法具有反应条件温和、产率高(72%～88%)和操作简单等优点.产物的结构通过IR,1HNMR和元素分析表征.A series of fluorene or phenanthrene derivatives were synthesized from arylaldehyde, malononitrile and 2-（1,2-dihydroinden-3-ylidene）malononitrile or 2-（2,3-dihydronaphthalen-4（1H）-ylidene）malononitrile catalyzed by KF/Al2O3 at 80 ℃ in ethyl alcohol. This method has the advantages of mild reaction conditions, high yields （72%-88%） and easy operation. The structures of the products were characterized by IR, ^1H NMR spectra and elemental analyses.
