  • Title: Highly efficient heterogeneous gold-catalyzed direct synthesis of tertiary and secondary amines from alcohols and urea.
    Author: He L, Qian Y, Ding RS, Liu YM, He HY, Fan KN, Cao Y.
    Journal: ChemSusChem; 2012 Apr; 5(4):621-4. PubMed ID: 22415929.
    Abstract:
    Urea, the white gold: The efficient synthesis of tertiary and secondary amines is achieved by heterogeneous gold-catalyzed direct amination of stoichiometric alcohols with urea in good to excellent yields. Via a hydrogen autotransfer pathway, the reactions of primary alcohols with urea give tertiary amines exclusively, while secondary alcohols selectively afford secondary amines.
