Title
Synthesis of a novel ionic liquid with both Lewis and Brønsted acid sites and its catalytic activities
Abstract

The novel ionic liquid with both Lewis and Brønsted acid sites has been synthesized and its catalytic activities for acetalization and Michael addition were investigated carefully. The novel ionic liquid was stable to water and could be used in aqueous solution. Furthermore, the molar ratio of the Lewis and Brønsted acid sites could be adjusted according to different reactions. The results showed that the novel ionic liquid was very efficient for the traditional acid-catalyzed reactions with good to excellent yields in short time.
