Nanocomposite of Fe3O4/Cellulose/Vitamin C as a New Biopolymer Catalyst for Synthesis of 1-(α-aminoalkyl) Naphthols, Betti Bases

Abstract

In this letter we report the synthesis of cellulose and vitamin C coated magnetite
nanoparticles (MNPs) as a green catalyst for the synthesis of pharmacologically active
1-(α-aminoalkyl) Naphthols via a one-pot condensation of 2-naphthol, alkylamines and
aldehydes under solvent-free conditions. The XRD results confirmed the pure
magnetite phase for the prepared MNPs. Morphological observations of the prepared
MNPs through SEM and TEM exhibited the uniform particle morphology with 15 nm in
size. IR analysis presented all vibrations related to chemical bounds in the cellulose and
vitamin C. TG analysis exhibits 12% vitamin C and 18% cellulose in MNPs composition.
Magnetic analysis via VSM proved the superparamagnetic nature of the prepared
MNPs.
