摘要
在乙醇钠存在下，４－乙酰基［２，２］对环番１与乙酸乙酯作用发生ｃｌａｉｓｅｎ酯缩合反应，生成β－二酮２，而与过量的氟乙酸甲酯反应则生成一个呋喃化合物３．文中提出了形成３的可能的反应历程并制备了化合物２，３的铜、镧、铈和格的螯合物．
Acetyl-[2, 2] paracyclophano reacts with excess ethyl acetate or methyl fluoroacetate under sodium ethoxide. In the first reaction, 1-(4'-[2, 2] paracyclophano) butanedione 2 is obtained, in the case of latter a furan derivative 3 is yielded. A multipile condensation and elimination mechanism was proposal for 3 formed. Some chef4ies of 2 and 3 are prepared.
