A series of novel chiral bisimidazolium and chiral bis(benzimidazolium) dichlorides with different substituents were synthesised effectively from the corresponding N-substituted imidazoles or N-substituted benzimidazoles with chiral (S)-2,2'-bis(2-chloroethoxy)-1,1'-binaphthalene in solvent-free conditions at ambient pressure. This protocol features a short reaction time, good yields, an eco-friendly process and easily control and handling. These compounds were fully characterised by NMR, IR and elemental analysis, and their specific rotations were given.
