以取代的芳基酮为原料, 合成了一系列6,6-取代芳基富烯, 这些富烯都经过了核磁共振、元素分析、质谱和红外光谱的鉴定. 芳基酮上的取代基决定了合成中所用碱的类型. 对于含吸电子取代的酮, 采用乙醇钠作为碱可以达到很高的产率, 而对于含烷基等推电子取代的酮, 用环戊二烯基钠直接反应是一种比较好的合成方法.

关键词: 碱, 富烯, 环戊二烯, 合成, 酮

Some new 6,6-diaryl fulvenes were synthesized from the diaryl ketones. Their structures were characterized by IR, 1H NMR, MS spectra and elemental analysis. The different substituents on the aryl ketones determined the different base used in the reactions. For the electron withdrawing diaryl ketones, EtONa was used as base to yield satisfied results. But for the electron donating diaryl ketones, it was a good method to synthesize fulvenes using CpNa as base.

Key words: fulvene, cyclopentadiene, base, synthesis, ketone
