چکیده مقاله :
In this research, the preparation of pyrrole derivatives using 2,5-hexane dione and aromatic first-type amine derivatives in the presence of borane trifluoride stabilized on nano kaolin was investigated under different conditions. Boron trifluoride immobilized on nano kaolin is readily available, heterogeneous, and recyclable. After preparation of the catalyst, it was detected using spectroscopy, imaging, and pattern-finding methods such as FT-IR, XRD, TGA, SEM, and TEM. In this research, N-aryl pyrrole derivatives were prepared using 2,5- hexane dione as raw material and aromatic first-type amine derivatives under different conditions [1-4] (Scheme1). Products were identified using spectroscopic ways such as FT-IR and 1H NMR. Among the advantages of this method is the use of affordable and available raw materials, high efficiency, short reaction time, and one-pot-reaction; ease of separation and purification of the products.
