Scandium can efficiently catalyze the solventless reaction of terminal epoxides with carbon dioxide in the presence of cetyltrimethylammonium bromide (CTAB) to give the corresponding five-membered cyclic carbonates in very high yields. Metal-exchanged montmorillonites proved to be an excellent and highly effective solution for the immobilization of Sc and Zn in this reaction. (C) 2009 Elsevier B.V. All rights reserved.
