摘要

在本研究中，我们的目的是研究新报道的MCM-41基纳米复合材料的催化作用，其中，通过锆纳米颗粒的稳定和磁化，这种介孔部分的低酸度得到了有利的改善，从而使其成为一种简单有效的处理方法。制备的Fe₃O₄@MCM-41 @ZrCI₂纳米复合材料通过不同的分析方法对其进行了表征，该复合材料可用于合成最突出的螺环化合物——螺环吲哚。正如预测的那样，Fe₃O₄@MCM- 41 @ZrCI₂对所研究的反应有相当大的促进作用。

Fe₃O4@MCM@ZrCI₂: A Practical Magnetic Mesoporous Zirconium-Based Nanocomposite as a Reusable Catalyst for the Synthesis of Spirooxindoles.

In the present study, we aimed to investigate the catalytic role of the newly reported MCM-41 -based nanocomposite in which the low acidity of this mesoporous moiety was favourably improved via the stabilization of zirconium nanoparticles and was magnetized to make a facile work-up procedure as an applicable and efficient method. The prepared Fe₃O₄@MCM-41 @ZrCI₂ nanocomposite was successfully characterized using different analyses and then it was favourably exploited for the synthesis of spirooxindoles as the most prominent spiro compounds. As predicted, Fe₃O₄@MCM- 41 @ZrCI₂ showed considerable efficiency in the promotion of the studied reaction.
