摘    要:
在可膨胀石墨催化下, 由芳香醛和5,5-二甲基-1,3-环己二酮缩合制备了3,3,6,6-四甲基-9-芳基-1,2,3,4,5,6,7,8-八氢化氧杂蒽-1,8-二酮. 在乙醇-水介质中回流反应2.5 h, 反应产率可达87%~93%. 该方法不仅反应时间短, 产率高, 而且催化剂价廉易得、对环境友好, 催化剂经简单过滤后可重复使用.

关 键 词:可膨胀石墨  芳香醛  5,5-二甲基-1,3-环己二酮  9-芳基-1,2,3,4,5,6,7,8-八氢化氧杂蒽-1,8-二酮

Abstract:
A novel synthesis of 3,3,6,6-tetramethyl-9-aryl-1,2,3,4,5,6,7,8-octahydroxanthene-1,8-dione via condensation of aromatic aldehydes with 5,5-dimethyl-1,3-cyclohexanedione using expansible graphite as catalyst was described.The reaction time was 2.5 h,and the yield ranged from 87% to 93%.The catalyst was inexpensive and environmental friendly,and could be recovered by filtration.
Keywords:expansible graphite  aromatic aldehyde  5  5-dimethyl-1  3-cyclohexanedione  9-aryl-1  2  3  4  5  6  7  8-octahydroxanthene-1  8-dione
