摘要：

A simple, efficient, and environmentally-friendly process has been developed for the synthesis of L-proline triflate ionic liquid (L-ProTfO) from L-proline and triflic acid using ultrasound irradiation. The combination of Lproline triflate ionic liquid technology with microwave energy represents an attractive and rapid alternative to the conventional acid-base-catalyzed thermal process. The current method has several advantages, including high yield, short reaction time, and work-up simplicity. In addition, the L-proline triflate ionic liquid could be recycled and reused four times without a noticeable decrease in catalytic activity. [GRAPHICS] .
