The products were obtained in a short time and good to excellent yields.</p> Dr. Nader Ghaffari Khaligh Fathiy Mutalabisin Copyright (c) 2023 Malaysian Catalysis-An International Journal 2023-09-06 2023-09-06 3 1 https://mcij.um.edu.my/index.php/MCIJ/article/view/44549 <p>The synthesis of a series of 3,3-diheteroaromatic oxindoles has been effectively produced through treatment of indole-2,3-dione (isatin) with various indoles and pyrroles using quaternized poly(4-vinylpyridine)iodinium iodide , under solvent-free condition and neutral medium. The reaction proceeds rapidly with excellent yields. This catalyst has been shown to be stable and highly recyclable.</p> SUZAIMI JOHARI NADER GHAFFARI KHALIGH Copyright (c) 2023 Malaysian Catalysis-An International Journal 2023-09-06 2023-09-06 3 1
