A Review on Polyaniline-Supported Catalyst for Organic Transformations.

Organic transformations are very important in synthetic organic chemistry and are used immensely in pharmaceuticals. Polyaniline is a marvelous and exceptional conducting polymer because of its extensive and valuable applications. Various modified polyaniline derivatives were developed by researchers and explored as solid heterogeneous catalysts for synthesizing important organic compounds through different organic transformations. Polyaniline-supported catalysts have many advantages: easy synthesis, environmental stability, environmental friendliness, high yield, short reaction times, the requirement for green solvent or solventless medium, and excellent reusability. In past years, polyaniline-supported catalysts have been widely used in various important organic syntheses under solvent-free or green reaction conditions. Hence, here is a comprehensive, detailed review of the application of polyaniline catalysts in organic transformations with all of their advantages and future scope.
