摘要

The three-component reaction of N-butyl-N'-phenacylbenzimidazolium bromide, aromatic aldehydes and 1,3-indanedione in ethanol in the presence of triethylamine as base catalyst resulted in the unusual charge-separated zwitterionic salts in good yields. Similar reactions with N-butyl-N'-(4-nitrobenzyl)-and N-butyl-N'-ethoxycarbonyl-methylbenzimidazolium bromide also afforded the corresponding zwitterionic salts. Furthermore, H-1 NMR spectra and single crystal structures indicated that the zwitterionic salts usually exist as two kinds of conformational isomers due to hindered interconversion of the different conformations.
