Polyaniline coated glass/SS sheet: Novel, convenient, efficient, reusable and green catalyst

•Polyaniline salt, coated on glass slide, rod, SS sheet as novel reusable catalyst•This method is very simple and efficient one.•Easy handling, ease of recovery, consistent activity of the catalyst•This methodology is energy efficient and a green benign procedure.

Polyaniline containing methanesulfonic acid dopant in semi crystalline with nano fiber morphology was synthesized easily in one step with excellent yield (1.26 g with respect to 1 g of aniline used), pellet density (1.32 g/cm3), and reasonably good conductivity (8.6 S/cm). PANI-MSA, formed in organic carrier solvent in the polymerization reaction, was coated on glass slide/glass rod/stainless steel sheet and used as novel reusable polymer based solid acid catalyst in the synthesis of α-aminophosphonates with excellent yields and the same glass slide was used for the preparation of various α-aminophosphonates.

Graphical abstractPolyaniline salt, coated on glass slide, rod, SS sheet, acts as novel reusable polymeric catalyst in organic synthesis. This methodology is economic, very simple, green benign and energy efficient.Figure optionsDownload full-size imageDownload as PowerPoint slide
