摘要

First, we investigated the efficacy of EAN compared to the most commonly used ionic liquids, [Bmim]PF 6 and [Bmim]BF 4 ([Bmim]=1??butyl??3??methylimidazolium); some organic solvents; and water by the model condensation between p??N,N??dimethylaminobenzaldehyde and Meldrum's acid. The experimental results summarized in Table 1 showed that the ionic liquid, EAN, was truly comparable with the other traditional solvents, [Bmim]PF 6 and [Bmim]BF 4 , with the ...
