摘要：
The synthesis process of 1,4-diazabicyclo(2.2.2) octane by reaction of ethylenediamine or monoethanolamine, for the first time, was achieved in the presence of ionic liquids. The comparative study showed that [Bmim][BF4] was more suitable to prepare 1,4-diazabicyclo(2.2.2)octane, with relatively high yield (up to 68.0%) and selectivity (ca. 72.6%). The reuse of [Bmim][BF4] was also studied. (c) 2008 Elsevier B.V. All rights reserved.
