application of sulfonic acid functionalized sba-15 as a nanoporous acid catalyst in microwave assisted synthesis of 2-aryl benzoxazoles
Authors
abstract
sulfonic acid functionalized sba-15 as a nanoporous acid catalyst was used in the synthesis of 2-aryl benzoxazoles 4 by the condensation of 2-aminophenol 1 and benzoyl chlorides 2 under microwave irradiation in solvent free reaction conditions. the advantages of this methodology are good product yields (60-98%), being environmentally benign, short reaction times and easy work up.

Here we present the first application of pore-expanded SBA-15 in heterogeneous catalysis. Pore expansion over the range 6-14 nm confers a striking activity enhancement towards fatty acid methyl ester (FAME) synthesis from triglycerides (TAG), and free fatty acid (FFA), attributed to improved mass transport and acid site accessibility.
