  • Title: Ionic liquid-supported aldehyde: a highly efficient scavenger for primary amines.
    Author: Muthayala MK, Kumar A.
    Journal: ACS Comb Sci; 2012 Jan 09; 14(1):5-9. PubMed ID: 22059585.
    Abstract:
    Novel aldehyde-functionalized ionic liquids have been synthesized and used as scavengers for primary amines in the synthesis of secondary amines. The yields of secondary amines are high (82-90%) with high purity. The advantages of the protocol over that with a polymer-supported aldehyde scavenger are the shorter reaction time, the homogeneous reaction medium, the high level of loading of the aldehyde group, easy monitoring of reaction, and characterization of intermediates.
