In recent years, there has been increasing emphasis on the design and application of environmental friendly solid acid catalysts to reduce the quantity of toxic wates, In this research covalentyl linked sulfonic acid (SO3H) modified g-C3N4 nanosheet catalyst was prepared. By the reaction of sythesized with 1,4 –butane-sultone, CN –BU-SO3H organocatalyst was produced. The synthesized organocatalyst was characterized by FTIR, EDX, XRD, FESEM and TGA analysis. The catalytic efficiency of the CN -BU-SO3H was investigated for the synthesis of 1,4-dihdropridine and polyhyroquinoline derivatives in hantzsch reaction and α-amino nitrile in strecker reoction.
The advantags of our method are as follows:
(1) The use of the inexpensive, efficient – envimmentalyl frindly organo catalyst (2) easy work up of the products (3) short reaction time (4) the use of the relatively enviromentally benigin Solvent.
Key words: Graphitic carbon nitride Nanosheet -1,4- Butanseultone – 1,4 dihydropyridine – polhydroquinoline – hantzsch reaction- α-amino nitril – strecker. reaction
