Synthesis and characterization of Fe3O4@SiO2@K10 NPs applicable for N-ter-butyloxycarbonylation using solvent-free conditions

Abstract

Abstract The present article gives the synthesis, characterization, and applications of K10 supported silica-coated ferrite nanoparticles. The analysis was done using XRD, FT-IR, EDX FE-SEM techniques. Then N-Boc protected amine derivatives were catalyzed by using K10 supported silica-coated ferrite nanoparticles. In the presence of di-ter-butyl carbonate aromatic amines, K10-supported silica-coated nanoparticles were shown to be a reusable nanocatalyst for N-ter-butyloxycarbonylation of amine derivatives, and 2 mol percent nanoparticles were sufficient for the reaction conversion. The prepared nanocatalyst has several benefits, besides a solvent-free reaction, high yield, eco-friendly catalyst, lower cost, and the ability to be recovered from the reaction and reused without reducing catalytic properties.
