摘要

利用多面体低聚硅倍半氧烷的衍生物 Octakis [3-(3-氨基丙基三乙氧基硅烷)丙基] octa-silsesquioxane(APTPOSS)的合成制备了一种高效的纳米复合材料。通过扫描电子显微镜、傅立叶变换红外光谱、振动样品磁力计、X 射线衍射和热重分析对 MNPs@Silica/APTPOSS 进行了表征。这些磁性纳米颗粒是有机-无机杂化多面体低聚硅倍半氧烷的组合,在螺吲哚衍生物的一锅合成中被用作高效的异相催化剂。此外,在保持催化效率的同时,它们还能被迅速分离并重复使用六次。

Silica/APTPOSS anchored on MnFe2O4 as an efficient nanomagnetic composite for the preparation of spiro-pyrano [2, 3-c] chromene derivatives

The synthesis of Octakis [3- (3-amino propyl triethoxysilane) propyl] octa-silsesquioxane (APTPOSS), a derivative of polyhedral oligomeric silsesquioxane, was utilized to produce an efficient nanocomposite. MNPs@Silica/APTPOSS was characterized through scanning electron microscopy, Fourier transform infrared spectroscopy, vibrating sample magnetometry, X-ray diffraction, and Thermogravimetric analysis. These magnetic nanoparticles, a combination of organic-inorganic hybrid polyhedral oligomeric silsesquioxane, were utilized as a proficient heterogeneous catalyst in the one-pot synthesis of spirooxindoles derivatives. Furthermore, they could be swiftly isolated and reused six times while maintaining their catalytic efficiency.

期刊介绍: BMC Chemistry, formerly known as Chemistry Central Journal, is now part of the BMC series journals family. Chemistry Central Journal has served the chemistry community as a trusted open access resource for more than 10 years – and we are delighted to announce the next step on its journey. In January 2019 the journal has been renamed BMC Chemistry and now strengthens the BMC series footprint in the physical sciences by publishing quality articles and by pushing the boundaries of open chemistry.
