A basic ionic liquid, 1-methyl-3-butylimidazolium hydroxide ([bmIm]OH), has been introduced as a catalyst and reaction medium for the Markovnikov addition of N-heterocycles to vinyl esters under mild conditions. The evidence for the role of this basic ionic liquid [bmIm]OH in promoting the Markovnikov addition has been given. On the basis of the evidence, a mechanism was postulated.
一种碱性离子液体，1-甲基-3-丁基咪唑氢氧化合物（[bmIm]OH），已被用作催化剂和反应介质，用于在温和条件下将N-杂环化合物马氏加成到乙烯基酯上。已经给出了这种碱性离子液体[bmIm]OH在促进马氏加成中作用的证据。基于这些证据，提出了一种机理。
