摘要
考察了LiClO4催化下,芳香醛与β-环己二酮的缩合反应。实验结果表明,催化量的LiClO4存在下,反应在78℃下进行2～3h即可高产率的得到氧杂蒽类化合物。该方法具有反应速度快、收率高和环境友好等特点,符合"绿色化学"的要求。
The reaction LiClO4 as a catalyst. It give xanthenediones 3 environmental friendly, of aromatic aldehydes 1 with β -cyclohexanedione 2 was investigated by using was found that the reaction can be completed smoothly at 78℃ in about 2 h to in good to excellent yield. The proposed method was fast, efficient and which was in line with ＂green chemistry＂.
