  描述：

  2,6-Difluoro-benzoic acid 2-acetyl-phenyl ester 在 sodium hydride 作用下， 以 二甲基亚砜 为溶剂， 反应 1.0h， 生成 1-(2,6-二氟苯基)-3-(2-羟基苯基)丙烷-1,3-二酮

  名称：

  Reinvestigation of prototropic photochromism: 3-benzoyl-2-benzylchromones

  摘要：

  The synthesis of a series of new nine 3-benzoyl-2-benzylchromones is developed through a classical and an optimized Kostanecki-Robinson method involving an o-hydroxyphenyl-beta-diketone and an acid anhydride. The different spectrokinetic studies carried out in solution and in polymer matrixes have highlighted the main structure/photochromic parameters relationships and the influence of the medium on the photochromic properties.
