Synthesis, Characterization and Catalytic Properties of Magnetic Nano Supported Molybdat Sulfuric Acid (Fe 3 O 4 @MSA NPs) in Base Catalyzed Synthesized of 2-Substituted aryl(amino) and (indolyl) Kojic Acid Derivatives under Solvent-free Conditions

Abstract

Magnetic nanoparticle-supported molybdate sulfuric acid (MNPs-MSA) was synthesized and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM). The catalytic activity of MNPs-MSA was investigated as a recoverable catalyst for the one-pot synthesis of novel 2-substituted aryl (amino) and aryl (indolyl) kojic acid derivatives from the reaction of aldehydes with aniline or indole and kojic acid in high yield at room temperature under solvent-free conditions Abstract should briefly state the purpose of the research, the principal results, and the major conclusions of the study.
