  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.

  Simultaneous application of the ultrasonic irradiation (US) and immobilized ionic liquid (IL@SBA-15) is used as an alternative to conventional catalysts in the Kabachnik-Fields reaction of an amine, aldehyde with phosphite leading to the formation of (alpha-aminoalkyl)phosphonate. The reaction time is reduced drastically and the reaction is progressed in an environmentally friendly way. The yields are around 93-96%. (C) 2014 Elsevier B.V. All rights reserved.
