This study focuses on the synthesis and characterization of a novel magnetic nanocomposite 2,4,6-trihydrazino-1,3,5-triazine (THDT)-functionalized with silica-coated iron oxide magnetic nanoparticles (MNPs). This nanocomposite has porous morphology decorated with the spherical MNPs. Through co-precipitation of iron salts, MNPs were obtained. The prepared THDT was placed on the chlorine surface-modified MNPs. The present environment-friendly nanocatalyst intensely accelerated the synthesis of highly functionalized tetrahydrobenzo[b]pyran derivatives as well as reduced the reaction times and increased yields of the products.

这项研究的重点是合成和表征新型的磁性纳米复合材料2,4,6-trihydrazino-1,3,5-triazine（THDT）-功能化的二氧化硅涂层氧化铁磁性纳米粒子（MNPs）。该纳米复合材料具有装饰有球形MNP的多孔形态。通过铁盐的共沉淀，获得了MNP。将制备的THDT放在氯表面改性的MNP上。本发明的环境友好的纳米催化剂强烈促进了高度官能化的四氢苯并[ b ]吡喃衍生物的合成，并缩短了反应时间并提高了产物的产率。
