A pyridine-based macrocyclic host for urea and acetone
摘要:
A pyridine-based macrocycle with a polyether chain has been designed and synthesized. The macrocycle shows strong binding for acetone involving both conventional and unconventional hydrogen bonds. The acetone in the cavity is exchangeable in CHCl(3) by urea. This has been studied thoroughly by (1)H NMR, (13)C NMR, mass and X-ray analyses. (c) 2008 Elsevier Ltd. All rights reserved.
