چکیده

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.
