    MgO-ZrO2 powder (MZ30) containing 30 wt% MgO was prepared by simple precipitation method. Two other catalysts were obtained by loading MZ30 powder with 5 wt% SrO and CsO using incipient wetness impregnation method. The catalytic performance of these catalysts was evaluated for synthesis of 2-amino-2-chromene via one pot three components condensation of benzaldhyde with malononitrile and ?-naphthol. Different techniques such as N2 physisorption, TGA-DTA, XRD, TEM, Hammet indicator method and CO2-TPD have been used to characterize the investigated catalysts. Reaction paameters such as reaction temperature, synthesis time and catalyst amount were studied to optimize the reaction conditions. The observed activity of these catalysts were correlated to their basicity and other surface parameters. Synthesis of 2-amino-2-chromene may involve moderate and strong basic sites of PKBH+ in the range .. Read More»
