Sonicated catalytically amount of the SBA-15/SO3H nanoreactor with organic substrate was found to be an efficient, ultra-fast and waste-free green approach for the synthesis of the indazolophthalazinetriones, polyhydroquinolines and alpha-aminophosphonates as models of organic reactions. The advantages of present combined method are the use of a low scale catalyst, simple procedure with an easy filterable work-up method, waste-free, green and direct synthetic entry to excellent yield of products in a high reusability and a short reaction time. SBA-15 nanoreactor anchored covalently bonded PrSO3H organic groups, to produce organic-inorganic mesochannels, in reaction condition (combined ultrasound/nanoreactor system) as catalyst provide a synergistic means of an efficient approach of the reactants to acidic sites, and suitable mesochannels to drive out the products and water for next recycles.
