FPS/[Fe(Bpy)3]2+ NPs as a nanocatalyst for production of quinoline-2-ones through the annulation of ortho-heteroaryl anilines and CO2

Abstract Carbon dioxide (CO2) play a basic role as a sustainable feedstock during chemical synthesis. The considered approach should be moderated to be viable. Iron(II) trisbipyridine complex [Fe(Bpy)3]2+ supported over fibrous phosphosilicate (FPS) utilizing dipyridin ligands has been determined as highly valuable catalysts of cycloaddition of ortho-heteroaryl anilines with CO2 during the synthesis of quinoline-2-ones. The mentioned materials possess various eco-friendly properties like high catalytic activity and easy to recovery from the reaction mixture using the method of filtration, and various reuse times without losing the efficiency.
