Direct synthesis, selective anion exchange, and DFT characterization of novel energetic heteroanionic dicationic ionic liquids

As outlined in Fig. 4, the parent HeDIL, 1,1ʹ-(2-hydroxy-1,3-propandiyl)bis[3-methyl-1H-imidazolium] chloride perchlorate, was synthesized from the one-pot pseudo-four-component reaction of 1-methylimidazole 1, epichlorohydrin 2 and perchloric…
