无溶剂、80℃条件下,无水硫酸铁可有效催化2-萘酚、醛、和胺/尿素三组分“一锅法”合成酰胺基烷基萘酚。考察了溶剂条件和催化剂用量对产率的影响。与已报道方法相比,该方法具有反应条件温和、反应时间短、产率高、不使用有机溶剂、催化剂廉价易得和后处理步骤简便等优点。 Without solvent, anhydrous ferric sulfate can effectively catalyze the synthesis of 2-naphthol, aldehyde and amine / urea three-component “one-pot method ” amidoalkylnaphthol under the conditions of 80 ℃. The effects of solvent conditions and amount of catalyst on the yield were investigated. Compared with the reported methods, this method has the advantages of mild reaction conditions, short reaction time, high yield, no organic solvent, cheap and easy to get the catalyst and simple post-treatment steps.
