Caesalpinia Sappan, Green Synthesis, MgO NPs, ADMP and Amino Alkyl Azide.Abstract
Azides have been considered as one of the energy rich functional groups as they are prominent precursors for reactive species like nitrenes and nitrenium ions. Also, they were utilized in synthesis of triazoles, triazolines and triazenes. The present work reports an eco- friendly synthesis of MgO NPs by utilizing Caesalpinia Sappan seeds as a novel fuel by solution combustion method. Multiple characterization techniques encompassing FTIR, UV- visible, XRD and SEM were used to study physico-chemical properties of synthesized MgO NPs. A convenient synthesis of amino alcohol via mixed anhydride method was carried out in the first step. Further, amino alkyl azide has been synthesized under mild condition by using the green synthesized MgO nanoparticles as a catalyst along with the addition of 2-azido-1,3-dimethylimidazolinium hexafluorophosphate, a safe, stable and efficient diazo transfer reagent. Structures of newly synthesized compounds were well characterized by HRMS, Proton and C-13 analysis techniques.
