ACS Sustainable Chemistry & Engineering. ACS Publications, Washington, DC, 2(7):1699-1706, (2014).
An efficient and benign protocol is reported for the synthesis of 4-methoxyaniline, medicinally important pyrazole derivatives, and Ullmann-type condensation reaction using magnetically separable and reusable magnetite-supported copper (nanocat-Fe-CuO) nanoparticles under mild conditions. Nanoparticles with average size of 40-50 nm have been synthesized using simple impregnation techniques in aqueous medium from readily available inexpensive starting materials and were recycled six times without loss in catalytic activity.
