Abstract

The tannic acid–based iron nanoparticle (TAN-Fe-NP) was prepared by a redox reaction between tannic acid and FeCl3 in water and characterized by the Fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, energy dispersive X-ray analysis, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy techniques. Then, a TAN-Fe-NP nanocatalyst was used as an efficient catalyst for the synthesis of polyhydroquinolines from the reaction of ethyl acetoacetate, benzaldehydes, dimedone, and ammonium acetate in ethanol at 60 °C in high yields and low reaction times. Since this catalyst is made of natural materials, it has a great advantage compared with the other catalysts and is cheap, available, natural, safe, nontoxic, and eco-friendly as well.

单宁酸基铁纳米粒子:一种绿色合成多对苯二酚的纳米催化剂

通过单宁酸与FeCl3在水中的氧化还原反应制备了单宁酸基铁纳米粒子(TAN-Fe-NP)，并通过傅里叶变换红外光谱、紫外可见光谱、能量色散x射线分析、x射线衍射、扫描电镜和透射电镜等技术对其进行了表征。然后，利用TAN-Fe-NP纳米催化剂作为高效催化剂，以乙酸乙酯、苯甲醛、二美酮和乙酸铵为原料，在60℃乙醇条件下以高收率、低反应时间合成了多对苯二酚类化合物。由于该催化剂是由天然材料制成的，因此与其他催化剂相比具有很大的优势，而且价格便宜、易得、天然、安全、无毒、环保。

期刊介绍： The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
