摘要：
The Morita-Baylis-Hillman reaction is an efficient carbon-carbon bond forming reaction for the preparation of alpha-methylene-beta-hydroxycarbonyl compounds. A new and highly active di-naphthalene imidazolium salt has been synthesized. We have found that 1, 3-bis[2-(naphthalene-2-yloxy)propyl]imidazolium bromid promoted the Morita-Baylis-Hillman reaction of various aryl aldehyde compounds in the absence of solvents. Our studies show that the Morita-Baylis-Hillman reaction by the influence of ionic liquid to give a high yield and short reaction time. (c) 2005 Elsevier Ltd. All rights reserved.
