Title

Synthesis and Characterization of MnO2/MgO Nano sheets: An efficient Recyclable Solid Base to Wittig Reaction

Abstract

Surface modification of MgO solid base is an important task in order to carry organic reaction for pollution free environment. For this purpose, MnO2/MgO mixed oxide nanosheets are prepared by alkali leached hydrothermal method at 150 OC for 48 hrs. As synthesized corresponding hydroxides are calcined at 450 OC for 6 hrs to form mixed MnO2/MgO. Mixed oxides are characterized by XRD, UV-DRS, IR, FESEM and EDS Analysis. XRD revealed formation of tetragonal crystal structure MnO2 mixed with cubic crystal system of MgO. FESEM shows formation of nanosheets of 20 nm thickness. Prepared mixed MnO2/MgO nanosheets are used as solid recyclable base in Wittig reaction of benzaldehyde and phosponium salt in DMF solvent at room temperature. Recycling of solid base is associated with no change in crystal phases and purity of materials. Surface activity after comparison with nanocrystalline MgO shows that higher valent Mn is responsible for enhancing surface basicity of MgO.

Key Words

MnO2/MgO nanosheets, Wittig reaction, surface basicity
