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.
