  • Title: Manganese(IV) dioxide-catalyzed synthesis of quinoxalines under microwave irradiation.
    Author: Kim SY, Park KH, Chung YK.
    Journal: Chem Commun (Camb); 2005 Mar 14; (10):1321-3. PubMed ID: 15742065.
    Abstract:
    We synthesize quinoxalines, catalyzed by manganese(IV) dioxide, from a variety of alpha-hydroxyketones followed by trapping with aromatic or aliphatic 1,2-diamines without using a solvent, within one minute under microwave irradiation.
