  Rediscovering the Double Friedel-Crafts Acylation: An Expedient Entry to Phenanthrene-9,10-diones

  摘要：

  The double Friedel-Crafts acylation of readily accessible biaryls with oxalyl chloride delivers the respective phenanthrene-9,10-diones, providing an alternative to the traditional methods, which require harsh oxidizing conditions and multistep sequences. This simple method allows the synthesis of various symmetrical and non-symmetrical targets, and is even effective for the synthesis of the parent ring system from (unactivated) biphenyl.

  The present invention has an object to provide a compound which has excellent compatibility even with a cellulose ester resin having a low acetylation degree, is capable of providing an optical film having a high Rth value and high bleed resistance, and can be suitably used as a retardation enhancer; a cellulose ester resin composition including the compound; an optical film including the resin composition; and a liquid-crystal display device including the optical film. The present invention provides an epoxy ester compound represented by the following Formula (1) (in the formula, R 1 to R 4 each independently represent an alkyl group having 1 to 3 carbon atoms; and A's each represent an aromatic group (a1) or an aliphatic group (a2) having 1 to 4 carbon atoms, and the average presence ratio [(a1)/(a2)] of the aromatic groups (a1) to the aliphatic groups (a2) is 99.9/0.1 to 80/20 in terms of a molar ratio).
