Development of new class of catalysts for the effective and green synthesis has always been a challenge for the researchers. Since heterocyclic chemistry depends both on homogeneous and heterogeneous catalysts, there is a scope for development of new catalysts. Keeping in view of the biological applications of heterocyclic compounds and for the development of greener methods of developing synthetic routes, magnetically separable nano nickel zinc ferrites have been applied for the synthesis of some heterocyclic compounds and their antibacterial activity had been studied. The Objectives of the Present Study 1. To synthesise Nano sized substituted spinel Nickel-Zinc Ferrites of the composition NixZn1-xFe2O4 x=0, 0.25, 0.5. 0.75 & 1 by sol-gel citrate precursor method. 2. To characterise the synthesized ferrites with FTIR, XRD, SEM, EDX, TEM and BET surface area techniques to interpret their structure and size. 3. To apply the synthesised ferrites as heterogeneous magnetically separable catalysts for the one-pot synthesis of ß-acetamido ketones. 4. To apply the synthesised ferrites as heterogeneous magnetically separable catalysts for the one-pot synthesis of ß-acetamido esters.
