  日期：1980.2

  The reaction of dilithium benzophenone and the lithium salt of benzophenone ketyl with anhydrides and chlorides and benzoic and acetic acid and the reaction of dilithium 9-flourenone with acetic anhydride were investigated. In addition to the expected products Ar2C(COR)OCOR, products of the type Ar2CCR(OCOR) were also obtained, and in the case of reactions with acetyl chloride and acetic anhydride

  研究了二锂二苯甲酮和二苯甲酮酮基锂盐与酸酐，氯化物，苯甲酸和乙酸的反应，以及9-氟烯酮二锂与乙酸酐的反应。除了预期的产品的Ar 2 C（COR）OCOR，类型氩产品2也得到CCR（OCOR），以及与所述类型的乙酰氯和乙酸酐，产品氩反应的情况下2CH（OCOR）。ESR研究表明，二苯甲酮二酮与乙酸酐的反应中形成了缩酮，而CIDNP方法表明，至少部分地，氢转移到由缩酮的O-乙酰化产生的自由基中形成了乙酸苄酯。结果表明加成反应和电子转移反应之间存在竞争。

• 1,1-Di(9-fluorenyl)ethyl acetate, a by-product from the acetylation of 9-fluorenyllithium
  作者：Paul D. Robinson、Hisham G. Lutfi、Yuqing Hou、Cal Y. Meyers

  DOI：10.1107/s0108270101001858

  日期：2001.5.15

  The preparation of sp-9-acetylfluorene from the reaction of 9-fluorenyllithium with acetyl chloride also provided 9-(1-acetoxyethylidene)fluorene ('diacetylfluorene') and 1,1-di(9-fluorenyl)ethanol, (II), as by-products recently characterized by X-ray analysis. A third by-product, 1,1-di(9-fluorenyl)ethyl acetate, (III), C30H24O2, has now been unequivocally identified for the first time, and emanates from the acetylation of the oxyanion of (II). In the asymmetric unit, compound (III) exists as two almost identical structures which differ slightly, but significantly, in conformation. Neither possesses the significant fluorene-ring bowing or the perpendicularity of the two ring planes exhibited by (II). The angle between the least-squares planes of the two fluorene rings of (III) is 58.45 (9) and 60.95 (10)degrees, respectively, for the two conformations, and their corresponding bonding parameters also differ slightly in a number of instances.
