Polyaniline mediated heterogeneous catalysis in the preparation of heterocyclic derivatives through carbon-heteroatom bond formations

Green-bond forming reactions in organic chemistry are very much essential for the sustainability and it is a continuous evolutionary process. Polyaniline (PANI) is one of the catalysts can offer a green-bond forming chemistry. The present chapter is designed to explain PANI mediated reactions leading to the synthesis of heterocycles. PANI and PANI-doped catalyst preparation methods and together with characterization of PANI catalyst using modern analytical tools is explained. Several heterocycles were prepared using PANI or doped-PANI catalyst in a one pot reaction conditions or sometimes multicomponent reaction conditions. Ease of PANI preparation, simple reaction conditions, PANI recovery and reusability and quick-way of product isolation or workup procedure are the highlights of this chapter.

Automated summary

Green-bond forming reactions using polyaniline (PANI) as a catalyst play a crucial role in organic synthesis. This chapter focuses on the preparation and characterization of PANI catalyst, as well as its application in the synthesis of heterocycles.
