    • The electrophilic activation of the aldehyde carbonyl is expected to take place through hydrogen bond formation with the C-2 hydrogen atom of the imidazolium moiety. In addition, molten-salt plays the electrophilic/ electrophilic-nucleophilic dual activation role for aza-Michael addition in the final step to form the product. Recently Chakraborti et al. have described an "eletrophilic nucleophilic dual activation" role of the ionic liquid. See ref. [29,30].
