Piperazinium Nano Silica Sulfonate: An Efficient Catalyst for the Hantzsch Reaction
Maryam Mousapour, Farhad Shirini
Abstract
Abstract Piperazinium nano silica sulfonate (PNSS) is simply prepared by the reaction of piperazine with nano sized silica sulfuric acid. After preparation it was completely characterized using different techniques including FT‐IR, XRD, TGA, FESEM, EDS and TEM analysis. In continue PNSS was efficiently used for the promotion of the synthesis of polyhydroquinolines and 1,8‐dioxo‐decahydroacridines through unsymmetrical and symmetrical Hantzsch condensation reaction. High yields, short reaction times, ease of preparation and reusability of the catalyst, easy work‐up procedure and solvent‐free conditions are among the most important advantages of this method.
