摘要
Dy(OTf)(3) immobilized in ionic liquids was found to be an efficient catalytic system for the reactions of indole with aldehydes/ketones or imines. Enhanced activity was observed. The use of ionic liquids as the reaction media allows facile separation and recycling of the catalyst. (C) 2004 Elsevier Ltd. All rights reserved.
