Abstract

In this investigation, a novel magnetic phosphonium ionic liquid (MPIL) was designed and synthesized through a two-step process. The resulting magnetic ionic liquid was fully characterized using different techniques including Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), derivative thermogravimetric analysis (DTG), energy-dispersive X-ray spectroscopy (EDX) and vibrating sample magnetometer (VSM). The prepared dual acidic MPIL represents brilliant catalytic performance towards the synthesis of 2′-aminobenzothiazolomethylnaphthol and amidoalkyl naphthol derivatives. Combination of magnetic, Bronsted and Lewis acid ability within a single compound is the major advantage of prepared MPIL. The present work can open up a new and promising insight in the course of rational design, synthesis and applications of task-specific multi-rule magnetic ionic liquids for various purposes.

摘要

在这项研究中，设计并通过两步过程合成了一种新型的磁性and离子液体（MPIL）。使用包括傅里叶变换红外光谱（FT-IR），热重分析（TGA），微分热重分析（DTG），能量色散X射线光谱（EDX）和振动样品磁力计在内的各种技术对所得的磁性离子液体进行了全面表征（VSM）。制备的双酸性MPIL在合成2'-氨基苯并噻唑并甲基萘酚和酰胺基烷基萘酚衍生物方面具有出色的催化性能。单一化合物中磁性，布朗斯台德和路易斯酸能力的结合是制备MPIL的主要优势。目前的工作可以在合理设计的过程中开辟新的前景。
