  In the study we reported synthesis of 2-aminothiophene derivatives in pure water using nano-structured Na2CaP2O7. Our results indicated that this heterogeneous catalyst performed good selectivity and catalytic activity in the synthesis of substituted 2- aminothiophene through Gewald reaction in water. The noticeable benefits of this procedure rely on several factors including: a simple method, mildness conditions, short time of reaction, operational simplicity and low cost. پرونده مقاله

  < p>Mg-Fe bi-metal oxide was prepared and utilized as a magnetized renewable solid base catalyst for formation of 2-aminothiophenes by means of Gewald’s reaction. The prepared heterogeneous basic solid catalyst can be separated by a magnet and reused without considerable wastage in this activity. The structure of the aforementioned magnetized basic nano-catalyst was studied by XRD (X-ray diffraction), SEM (scanning electron microscopy), TEM (transmission electron microscopy), EDS (energy dispersive x-ray spectroscopy) and VSM (vibrating sample magnetometry) techniques. The present methodology offers several advantages such as high yields of products, shorter reaction times, environmentally friendly conditions, low catalyst dosage, high endurance and facile work-up. پرونده مقاله
