Bimetallic Pd–Au/TiO2 Nanoparticles:
An Efficient and Sustainable Heterogeneous Catalyst for Rapid Catalytic
Hydrogen Transfer Reduction of Nitroarenes
Posted on 2018-10-11 - 14:38
Anilines are one
of the important chemical feedstocks and are utilized
for the preparation of a variety of pharmaceuticals, agrochemicals,
pigments, and dyes. In this context, the catalytic reduction of nitro
functionality is an industrially vital process for the synthesis of
aniline derivatives. Herein, we report an efficient nanosized bimetallic
Pd–Au/TiO2 nanomaterial which is proved to be quite
efficient for rapid catalytic hydrogen transfer reduction of nitroarenes
into corresponding amines. Significantly, the reduction process is
successful under solvent-free and mild green atmospheric conditions.
Bimetallic Pd–Au nanoparticles served as the active center,
and TiO2 played as a support in hydrogen transfer from
the source hydrazine monohydrate. Typical results highlighted that
the reactions were very rapid and the products were obtained in good
to excellent yields. Significantly, the process was successful in
the presence of a very low amount catalyst (0.1 mol %). Furthermore,
the reaction showed good chemoselectivity and compatiblity with double
or triple bond, aldehyde, ketone, and ester functionalities on the
aromatic ring. Typical results indicated the true heterogeneous nature
of the Pd–Au/TiO2 nanocatalyst, where the catalyst
retained the activity, without loss of its activity.
