Iron-Oxide-Supported Ultrasmall ZnO Nanoparticles: Applications for Transesterification, Amidation, and O‑Acylation Reactions
An
efficient maghemite–ZnO nanocatalyst has been synthesized
via a simple coprecipitation method, where ZnO nanoparticles are uniformly
decorated on the maghemite core and characterized by XRD, SEM-EDS,
ICP-AES, XPS, TEM, HRTEM, and Mössbauer spectroscopy; maghemite
nanoparticles are in the typical size range 10–30 nm with ultrasmall
(3–5 nm) ZnO nanoparticles. A competent and benign protocol
is reported for various organic transformations, namely, transesterification,
amidation, and O-acylation reaction in good to excellent yields (75–97%)
using magnetically separable and reusable maghemite–ZnO nanocatalyst
