摘要：
A magnetically ionic liquid supported on gamma-Fe2O3 nanocatalyst (AlxCly-IL-SiO2@gamma-Fe2O3) was synthesized and evaluated as a recoverable catalyst for the synthesis of beta-keto enol ethers. The immobilized catalyst proved to be effective and provided the products in high to excellent yield at room temperature. Moreover, the catalyst could be easily recovered by magnetic separation and recycled for six times without significant loss of its catalytic activity. (C) 2013 Elsevier B.V. All rights reserved.
