摘要：
An efficient one-pot procedure for the synthesis of ionic liquids based on nitrogen-containing heterocycles, imidazolium or pyridinium under 'green chemistry' conditions has been described Imidazolium salts and DBU have been found to catalyze efficiently the berizoin condensation giving good yields within very short reaction time using solvent-free microwave activation conditions (C) 2009 Elsevier Ltd All rights reserved
