摘要 1,3-Dibromo-5,5-dimethylhydantoin，为 14-aryl-14H-dibenzo 的合成被用作有效催化剂[一， j ] 氧杂蒽面对白陶土。所有反应在相对短的反应时间当溶剂不在时被执行在对高收益好。 1,3-Dibromo-5,5-dimethylhydantoin, has been used as an efficient catalyst for the synthesis of 14-aryl-14H-dibenzo[a,j]- xanthenes in the presence of kaolin. All reactions are performed in the absence of solvent in relatively short reaction times in good to high yields.
