In this work, catalytic efficiency of palladium niacin complex immobilized on starch-coated maghemite nanoparticles successfully exploited for homo- and cross-coupling reactions such as Suzuki–Miyaura, Sonogashira-, and Ullmann coupling reactions. The solid catalyst characterized by different methods such as FT-IR, TGA, XPS, EDS and ICP-AES. TEM images revealed a nanosize structure for catalyst and vibrating sample magnetometer (VSM) demonstrated its magnetic property. The reactions proceeded well in the absence of commonly used additives with high selectivity. Potential reusability of magnetically separable palladium catalyst and performing the reactions at environmentally conditions are notable features of the present methods making great potential for practical applications.Graphical Abstract
