摘要
制备了一种新型改性活性炭负载Fe Cl3催化剂(MAC-Fe Cl3),并通过红外光谱及等离子体发射光谱等技术手段对其进行了表征。在MAC-Fe Cl3催化下,β-萘酚与醛在PEG200中,于120℃反应60~120 min,合成了一系列氧杂蒽类衍生物,收率为79%~93%。该方法操作简单、产率高、环境友好。制备的催化剂性能稳定,使用4次仍保持较高活性。
A novel modified active carbon supported ferric chloride catalyst( MAC-FeCl3 ) has been prepared and characterized by IR and ICP-AES. In the presence of MAC-FeCl3, condensation of aldehydes and β-naphthol was carried out in PEG 200 to afford a series of xanthene derivatives in 79% - 93% yields within 60 - 120 min. The prepared catalyst can be recycled easily and the activity of catalyst maintains stable after used for 4 times. This affords this methodology the advantages on good yields, less pollution and simple workup.
