Kothandapani J, Ganesan SS. Concise Review on the Applications of Magnetically Separable Brønsted Acidic Catalysts. CURR ORG CHEM 2019.

Abstract
Magnetically separable Brønsted acidic catalysts combine the advantages of
high efficiency of homogeneous Brønsted acidic catalyst with the ease of magnetic
separation from the reaction medium. In addition to their ease of separation, the
magnetically separable Brønsted acidic catalysts also possess high stability towards air
and moisture, facile functionalization and tunable hydrophobic properties. This review
portrays the applications of sulfonic acid anchored γ -Fe2O3 or Fe3O4 nanoparticles,
magnetic core encapsulated acid functionalized silica or mesoporous nanoparticles,
functionalized ionic liquid coated acidic magnetically separable nanoparticles and
miscellaneous magnetically separable Brønsted acidic nanoparticles in diverse organic
transformations. In addition, the merits of magnetically separable Brønsted acid
nanocatalyst are also summarized and compared with the traditional homogeneous/heterogeneous Brønsted
acidic catalysts.

Abstract
A new preparation of 1,5-benzodiazepine derivatives has been achieved in good to excellent yields by the condensation of o-phenylenediamine with a variety of ketones employing nano-γ-Fe2O3–SO3H as catalyst under microwave irradiation and solvent-free conditions. Recyclable nano-γ-Fe2O3–SO3H provided high reactivity and was easily separated from the reaction mixture by using an external magnet. The advantages offered by this method are based on the principles of ‘green chemistry’: a facile and rapid reaction, no solvent, easy separation of products and good to excellent yields..
